This PR fixes an assertion error when the physical-logical map changes during key synthesization. This error will lead to irregular key sequences, and might occur during an extremely rare edge case described in the unit test in this PR.

 This PR changes how embedder API's SendKeyData sends ui.KeyData to the framework. The packets are now sent over the existing platform messenger, reusing the entirety of its code path and functionalities while keeping the embedder API unchanged

…#29727)

Fixes flutter/flutter#93352

Improves Android benchmarks on both Pixel 4 and a lower end Android Go device for 99th percentile and average raster times.

This works by telling the system compositor what timestamp we intended to show this frame for. This way, if we end up with a frame that gets submitted right at the beginning of a vsync and then a second frame submitted on the same vsync, the compositor will only try to show the second frame on the screen and save the GPU some work.

Without this, a situation like that results in an "avalanche" of calls where the GPU is behind the CPU and keeps delaying CPU work until we finally stop submitting frames. This can be observed as a lengthy dequeuBuffer in a systrace enabled trace, as shown in the linked issue. This avalanche is often triggered by a frame that does a shader compile through a couple vsyncs and then is followed by a bunch of very fast frames that take less than a vsync to render - the first of those fast frames gets delivered before the end of the vsync that the slow frame ended in.

We cannot implement this ourselves because we don't know how long the swap buffers call will take on the system side, and if we try to guess we can very well get it wrong.

I've filed issues to look into adding this for Vulkan and Metal, although we should also first take traces there to make sure it's warranted.

The shell tests are failing on Windows against the latest VS2019 headers due to a new safety assert.

Dart VM flags are passed to Flutter via an fml::CommandLine::Option that
looks something like:

   {"dart-flags, "--max_profile_depth 1,--trace_service"}

We perform a prefix match to handle cases where Dart VM options take
arguments.

Adding the comment since in a recent review I found myself wondering why
we're using a prefix match to begin with. While the original author had
forgotten, the good news is, he wrote a test that covers this exact
case. This comment just removes one level of indirection for future
readers.
