go/flutter-fuchsia-packaging contains more details about the layout

* Disabled GPUThreadMerger tests.

* switched to a single gtest_filter argument

Put `Picture.toImage` back on the GPU thread.  Left the unit tests intact.

When gr context is changed (this happens when sending the app to the background and then to the foreground) we need to update it for all the platform view overlay surfaces.

The update logic was caching the previous gr context to figure if it had to be updated, but after updating it for a given overlay we were updating the cached context. In apps with multiple platform views this will result in overlays with a stale gr context.

This fixes flutter/flutter#36437
And I believe it should fix flutter/flutter#36999 as well (though I don't have repro code to verify).

Fixes: https://github.com/flutter/flutter/issues/43926

Pass the automaticallyRegisterPlugins flag to the FlutterEngine constructor in FlutterActivityTest (#13468)

* get the size from visualviewport instead of window.innerHeight/innerWidth.

* merging 2 if statements to one.

* add more comments

The fd passed to fdopendir will be unusable afterward.  Using a duplicate
preserves the validity of the original directory fd passed to VisitFiles.

Fixes https://github.com/flutter/flutter/issues/43844

Having 2 or more platform views simultaneously in the layer tree was crashing immediately on iOS with GL backend.

This regressed in #11070 which passed gl_context to a function in a loop using std::move (which meant on the second iteration the caller is no longer the owner of the field).

I added a scenarios_app test, though this test doesn't run on a physical device on CI so it would have only caught the problem when running locally (flutter/flutter#43852).
