This CL introduces dart_api_dl.h which exposes a subset of dart_api.h
and dart_native_api.h for dynamic linking at runtime through the FFI.
Dynamic linking is done through including dart_api_dl.cc in a shared
library and passing NativeApi.initializeApiDLData to the init function.
This CL also includes Native API versioning to deal with possible
version skew between native api version against which native libraries
are compiled and the version in the DartVM the code is run on.
The subset of symbols in the CL includes handle related symbols, error
related symbols, handle scope symbols, and native port sumbols.

The flutter engine DEPS got new icu/boringssl so this CL can safely
land and roll into engine. A small change is made in Patchset 1..3.
This removes special logic for creating the `dart-sdk` we distribute
which used to build release and product mode and copied some binaries
from the latter into the former, before the SDK was actuallly ready to
test and distribute.
This changes the GN build rules to build the necessary
gen_snapshot/dart_precompiled_runtime product binaries during the normal
release build.
Normally during --mode=product builds the global build config in
//build/config/BUILDCONFIG.gn will set `-fvisibility=false`.
=> Doing so results in much smaller binaries - because only explicitly
exported symbols are visible, the rest can be tree shaken by the linker.
Since we are building --mode=release, the `-fvisibility=false` will not
be set. In order to set the flag for the 2 special product-mode binaries
we need to add -fvisibility=hidden manually, in:
* dart_product_config: Which is used for compiling VM sources.
* 3rd party double-conversion library
* 3rd party boringssl library
* 3rd party icu library

* BoringSSL: https://dart-review.googlesource.com/c/boringssl_gen/+/150482

This includes support for calling Dart_PropagateError in native code
when doing FFI calls, and catching uncaught exceptions with Dart_IsError
when doing FFI callbacks.
The support for Dart_PropagateError adds a catch entry to the FFI
trampoline, which prevents inlining these trampolines in AOT. This
regresses the FfiCall benchmarks by 1-2% in AOT.
In addition, Dart_PropagateError requires maintaining a bit whether we
entered native/VM code from generated code through FFI or not. That way
we can do the proper transition on the exception path. When entering
generated code, we store this bit on the stack, right after the entry
frame.

Today, Stdout and Stderr have a property supportsAnsiEscapes. The
documented purpose of this property is to inform the caller whether ANSI
escape sequences are supported - say, for colorizing terminal output
when the user is running the Dart program in a terminal emulator like
xterm.
The problem is that the heuristic used is a substring match for "xterm"
in the TERM environment variable. (See attached bug.) This
implementation omits a few significant populations of users:
* Users using screen or tmux. These commands set their TERM to "screen".
* Users using a non-xterm terminal like rxvt (especially rxvt-unicode).
The correct solution here is to query terminfo for terminal
capabilities. Until then, adding these two cases to the existing xterm
check unblocks users of two popular terminal multiplexers and a terminal
emulator.

The relocated addresses are populated during BSS::Initialize() for
natively loaded ELF snapshots, and during the non-native loader when it
is used. Putting this information in the BSS segment avoids having to
change the embedder interface, since we only need this information for
AOT snapshots. This also avoids depending on our ELF snapshot layout
to reverse-engineer the DSO base for ELF-compiled snapshots.
We now always print the DSO base for both the VM and isolate in
non-symbolic stack traces, not just for ELF-compiled snapshots. However,
we still only print the relocated addresses in individual stack frames
if we're guaranteed they match those in separately saved debugging
information.

To avoid deadlock scenarios where an application runs N isolates on a
thread pool with T threads (T < N) where all scheduled T isolates will
do FFI call and block. That prevents any other isolates from executing.
To avoid such a scenario we add support for the isolate-group specific
thread pool to dynamically increase the maximum size if a worker is
running a isolate mutator thread, which calls to C which exits the
isolate.
=> While such an isolate is descheduled but still occupies a thread
pool worker we temporarily incrase the maximum size of the thread pool.

In order to reduce confusion, if a VM instance detects that it will be
running a dartdev snapshot it will ignore all VM flags and print a
warning message to stderr informing users that the flags are being
ignored and that they should be passed immediately after the 'dart run'
command. This will prevent the dartdev snapshot from being run with
incompatible flags in addition to preventing users from accidentally
setting flags for the dartdev VM when they meant to set those flags for
the target process.
As usual, passing --disable-dart-dev will allow for the user to bypass
this behavior and run their dart program directly.

Windows paths are limited to 260 characters including the null
terminator in most cases. This makes characters in paths
a precious commodity.
Currently creating a temporary directory in Dart will append
a UUID to the user-provided prefix. UUIDs consume 36
characters of a path. If a temporary directory is created
inside of another temporary directory, this adds up to 72
characters or about 28% of the available real estate.
This change first attempts to use a shorter suffix generated
from a random uint32_t using Crypto::GetRandomBytes. If
that fails, then it falls back on using the UUID.

- Flips the flag from --nnbd to --no-nnbd so that by default it builds
the NNBD version
- using the --no-nnbd flag results in the SDK being built in a
directory which has the 'Legacy' suffix added to it
(e.g: out/DebugX64Legacy)
- the '--enable-experiment=non-nullable' flag still needs to be passed
in during execution so that CFE runs in that mode. This is different
from the 'null_safety' flag

Prior to this CL, the signal handler finalizer passes a file descriptor
where a signal number is expected.
This went uncaught for awhile since it is innocuous in most cases.
Clearing a signal handler just involves setting it back to the
default. It is not innocuous where the VM chose to override the
default, for example in the case of SIGPIPE. When setting signal
handlers with the dart:io API, if the finalizer for a _NativeSocket
for a signal handler runs, some time later the VM may be killed by
SIGPIPE instead of getting EPIPE from an IO call.
This CL replaces the call in the finalizer with a new call that
expects a file descriptor, and uses the file descriptor to look
up the signal handler that needs to be cleaned up.

Running the standalone VM in the following ways will result in the
DartDev help message being shown:
- `dart`
- `dart --help`
The following will output the VM help message:
- `dart run`
- `dart help run`
- `dart --help --verbose` (includes verbose VM flags)
- `dart help run --verbose` (includes verbose VM flags)
- `dart run --verbose` (includes verbose VM flags)
The original standalone VM behavior can be restored by providing the --disable_dart_dev flag.

The startup info structure includes a pointer to an array of IO handles;
this was made from the address of a local variable with a scope that
ended before the call to CreateProcessW, leading to undefined behavior.
In practice this appears to have mostly been working, but it reliably
fails under some build configurations of Flutter using clang.
This gives that array the same lifetime as the rest of the arguments to
CreateProcessW.
