This reverts commit 8acc058cf1.
Reverts #25483
Reason for revert: it seems to break the flutter_gallery_instrumentation_test post-submit test.
TBR: @sbaranov
This updates the test to match the engine API change introduced in:
https://github.com/flutter/engine/pull/6081
This also rolls the engine, the roll includes only the relevant engine commit:
```
091492601 Allow passing extra creation parameters for embedded Android views. (#6081)
```
The test places an embedded Android view at the top left, and verifies
that motion events that get to FlutterView are equivalent to the
synthesized motion events that gets to the embedded view.
See the README.md for more high level details.
