Chinmay Garde 15798a885b Fix race condition and data race in FrameInfoContainsValidWidthAndHeight. (flutter/engine#20706) ...

The data race: gl_surface_fbo_frame_infos_ in the test context to was appended
to on the raster task runner but read on the platform task runner. This is now
sidestepped by using a callback and pushing that responsibility to the test.
Setting the callback is guarded behind a mutex.

The race condition: The assertions were previously run when the UI thread was
done generating the frames. However, the assertions were run on the results
collected on the raster thread in response the frame requests from UI thread.
Just run the assertions on the raster thread directly.
