GObject's dispose() method may be called multiple times. Guard against
trying to disconnect the same signal multiple times by clearing the ID
to avoid warnings when closing the window.

This crash has come up a number of times and we tend to
burn time looking in the wrong places for the fix. Documenting
some stuff about how we've fixed it previously in the error
message.
* Include checkbox in check state update
* Windows test for checkbox native state
* Reformat to appease linux_unopt test
* More format hoops

When setting FlutterProjectArgs.command_line_argv prior to launching the
engine, we were previously setting a placeholder value rather than the
executable name. This resulted in Platform.executable (from dart:io)
returning "placeholder" in application code.
This updates the Windows implementation for consistency with macOS and
guarantees that Platform.executable will return a reasonable value in
Dart code.
Note that this does not affect Platform.resolvedExecutable, which returns
a full, resolved path, and is implemented in the Dart runtime itself.
Previously the code:
print(Platform.executable);
print(Platform.resolvedExecutable);
resulted in the following output on Windows:
flutter: placeholder
flutter: C:\path\to\project\build\windows\runner\Debug\project.exe
after this patch, it results in:
flutter: project.exe
flutter: C:\path\to\project\build\windows\runner\Debug\project.exe
Issue: https://github.com/flutter/flutter/issues/83921
Update Picture rasterization for toImage to accept a layer tree, optionally flattening on the raster thread if present.
Update Deferred GPU image for toImageSync to accept a layer tree, flattening it the first time it creates an image, storing the resulting display list.
This is also a performance fix for the zoom page transition, which currently does too much work on the UI thread on frame 1
Migrates error logging from logging directly to stderr to using the
FML_LOG macro with a specified log level.
No additional tests since there is no semantic change to the logging
(FML_LOG simply writes to stderr).
Adds the ability to register native functions for use in test fixtures.
This allows registering native C++ functions that can be invoked from
Dart code to perform the following common actions:
* Signal a waiting latch in the C++ part of the test.
* Pass data back to the C++ part of the test.
* Allow the C++ part of the test to pass data to the test.

channel closure.
This CL resets the state including cleaning up the buffers whenever
a fuchsia.ui.pointerinjector.Device channel closes due to some error.
