[Android] Add display corner radii support. (#179219)
Closes https://github.com/flutter/flutter/issues/97349
Unblocks https://github.com/flutter/flutter/issues/178463

### Description

This PR focuses only on the Android side.

As was discussed in https://github.com/flutter/flutter/issues/97349, the
iOS API for getting display corner radii is private. The only safe way
to get the radii values is to generate a lookup table ahead and use its
values at runtime. I would be happy to work on the iOS implementation in
a separate PR after this lands.

- Adds `displayCornerRadii` in the physical pixels to the engine's
window metrics
- Adds `displayCornerRadii` support on the Android API 31+
- Adds `displayCornerRadii` in the logical pixels to the `MediaQuery`
- Adds and updates tests
