We were exporting all symbols to the dynamic table so that they could be looked up using `dladdr` for the profiler and backtracer. The symbols include our statically-linked libcxx, which can create trouble when another DSO has a different version of libcxx. Now we export only the VM embedding API functions (`Dart_*`) and use a specially produced table to do the symbolization.

Reason for revert: One of the new tests spawns a process and runs the script from source and so this test will fail on all AOT configurations, In addition it is failing on mac builds and needs investigation.

This adds [sendMessage] and [receiveMessage] methods to [RawSocket] class. They are only supported on Linux at the moment as they require connection opened as unix domain socket connection.
This introduces [SocketControlMessage] class that represents a message sent via socket and also introduces [ResourceHandle] class that wraps [RandomAccessFile], [Socket]/[RawSocket]/[RawDatagramSocket], [Stdin]/[Stdout] for
marshalling/unmarshalling purposes.
Underlying OS implementation supports various kinds of control messages that can be passed via sockets, this CL only adds support for sending/receiving opened file description handles.
When receiving a message recipient can attempt to extract handles out of it via [tryExtractHandles]. It returns [null] if message has no handles to extract.
This is continuation of the work started on https://dart-review.googlesource.com/c/sdk/+/205067.

Support Unix domain sockets communication on Linux, MacOS and Android.
Changes:
1. Add a field for InternetAddressType named unix.
2. Constructor of InternetAddress gains one more optional field: type. InternetAddress(String address, {InternetAddressType type});
3. Add another constructor to InternetAddress which taks raw address/path for ip/unix addresses as an argument. InternetAddress.fromRawAddress(Uint8List rawAddress, {InternetAddressType type});
The operation for unix domain sockets communication is basically the same as normal sockets except an InternetAddress with type unix should be passed.

Prior to this change, on Linux, if one created a symbolic link to the
dart executable and ran that, the kernel-service snapshot would not be
found. This has the effect of compiling the input script on a
non-trained kernel service, meaning the startup is slower.
This is particularly bad as the debian install of dart creates a symbolic
link to dart as /usr/bin/dart with the target being /usr/lib/dart/bin/dart
meaning that for instance running a hello-world script like one normally
would, `dart hello.dart` would take something along the lines of 3-4 times
longer than if running `/usr/lib/dart/bin/dart hello.dart`.
On my Pixelbook (in crostini) this is ~755 ms vs ~210 ms.
This change does *NOT* fix it on other platforms.

- On Fuchsia, it caches the fd from fdio_ns_t instead of recomputing it
on every fs access.

Fuchsia requires the ability to sandbox Isolates w.r.t. file IO.
When a new Isolate starts, Fuchsia will pass the Isolate an object
called a namespace. We can translate the namespace object into a
file descriptor suitable for passing to the *at() family of
POSIX file system calls. The file system calls will then
have visibility only into the specified namespace.
We also plumb Namespaces through on all the other platforms as well to
make the change easier to test and so that in the future we can
implement e.g. per-isolate cwds.
This change adds a new internal class to dart:io called _Namespace,
which is implemented in a patch file. See:
sdk/lib/io/namespace_impl.dart
runtime/bin/namespace_patch.dart
The embedder can set up a non-default namespace by calling
_Namespace._setupNamespace during Isolate setup.
Instances of _Namespace have a native field that holds a pointer
to a native Namespace object. See:
runtime/bin/namespace.h
Calls from e.g. file_impl.dart are now also passed a
_Namespace object. The implementations in e.g. file.cc and
file_linux.cc then extract the namespace, and use it to compute a
file descriptor and path suitable for passing to e.g. openat().

This CL changes File::Write on Windows to call directly to WriteFile()
instead of using _write(). This avoids a number of complexities:
1. Don't need to bother with text vs. binary mode.
2. Don't need to check both errno and GetLastError if _write() fails.
3. Don't need to convert to a wchar_t* for console output since we've
already set the code page to UTF8.

- Set the file translation mode to _O_WTEXT when writing to a
