This change, and the code introduced, is probably not going to be required
once the platform kernel file is linked into the executable.

The isolate creation callback flow was using DFE::kernel_file_specified()
to decide whether to load kernel program or not. However, since this flag
is not isolate specific, it was causing problems in the case where a dill
file was passed as the main dart program; the other isolates, even if
they were loading a snapshot, were looking for a kernel program.
This change was originally submitted as
"Make the decision, on whether to start the kernel isolate, liberal." It
was reverted due to failures on simdbc bots. This change is another
attempt which fixes those failures.

The content handlers on Fuchsia can potentially give each Isolate
different handles to use for stdout and stderr. This change provides
a hook for an embedder to call to supply the handles to Dart, and
removes hardcoding of stdio handles to 0, 1, 2.

This reverts commit 8986a85426.
Reason for revert: This broke our sim* builders, for example:
python tools/test.py -mdebug -c dartk -a simdbc64 service/next_through_assign_int_test
...
../../runtime/bin/main.cc: 202: error: expected: kernel_program != NULL
...
Unfortunately our sim* builders don't send out emails to authors because
they were setup with the new LUCI infrastructure. This causes failures
like this to not get noticed in time.

Some parts of the Dart build need to be customized when running the
host steps for a build ultimately targeting a Fuchsia build. This was
set by passing a special GN variable indicating that a configuration
was a host configuration targeting a Fuchsia build, but the built-in GN
variable 'target_os' has the same result as it is the same across all
toolchains in a particular build. This replaces the test:
is_fuchsia || is_fuchsia_host
with the equivalent:
target_os == "fuchsia"
and the less common:
is_fuchsia_host
with:
target_os != current_os && target_os == "fuchsia"

This linked in kernel service dill file will be used to load the kernel
isolate if the attempt to lookup the kernel service snapshot fails. The
kernel service snapshot is looked up in the following order.
1. If the "--dfe" option is specified, the file specified is used.
2. If the kernel service snapshot is found next to the executable,
then it is used.
3. If the kernel service snapshot is found in the "snapshots" directory
next to the executable, then it is used.

Adding a dependency file triggers resolving its file path using the
service isolate. However, in the kernel flow, gen_snapshot does not
initialize the service isolate. This does not seem to cause any problems
on Mac and Linux, but flutter crashes on Windows. On Linux and Mac,
the behaviour with this change matches the current behavior.
The correct dependency file to add to the dependencies file in the kernel
flow is the app dill file passed as input to gen_snapshot. But, this would
call for specifyint the application sources as the dependency for the app
dill file itself somewhere. We can revisit this and fix it up correctly if
needed. For now, this change unblocks the Windows builds.

In 5a44162c97 in attempt to adhere to declared
method signatures we lost zero-copying JSON decoding of responses from
VM: `Message.sendToVM` was changed to always decode the response into
string before passing it to the caller and the logic to use fused
JSON decoding was removed. This increased peak memory consumption by
the VM Service.
This commit addresses the issue by restoring the zero-copying JSON decoding
logic while adding a wrapper around responses that make it clear what kind
of data is passed around and how that data is encoded and handled.
We introduce a class `Response` which can contain either a Dart string, a
binary data (represented as a Uint8List) or utf8 encoded string (represented
as a Uint8List). This class is used in all places where previously a String
or dynamic were used, e.g. MessageRouter.routeRequest is changed to return
Future<Response> rather than Future<String>. This allows callees to
decode JSON responses without copying them into Dart heap while
maintaining sufficient level of typing to make the code easy to reason about.
This commit also removes some dead code from the VM service related to old
Service API and TAR assets unpacking (which has been long done in C++).

The only fix needed for relanding is adding _ensureScheduleImmediate
to the list of vm entrypoints in //runtime/vm/compiler/aot/precompiler.cc
Original commit message:
Adds a top-level call waitForEventSync to dart:io that blocks the
thread an Isolate is running on until messages are available.
Before the thread blocks, the microtask queue is drained.
Before waitForEventSync returns, all messages are handled.
Lifting this up from a comment:
This is apropos of the request that nweiz@ sent to the mailing list a
couple weeks back. I'm not sure we should land this. We certainly
shouldn't land it without some annotations that will make the analyzer
complain a lot in most configurations, but I don't know what those
annotations are.
