[web] Fix stack corruption in Skwasm and harden withStackScope API - #182912

…lutter#182912)

This PR fixes a critical memory crash in Skwasm. The root cause was the
incorrect usage of `withStackScope` with an `async` closure in
`SkwasmSurface.rasterizeToImageBitmaps`.

Because `withStackScope` restores the WASM linear memory stack
immediately after the closure returns, any asynchronous yields (waits)
inside the closure would cause the stack to be reclaimed while the
closure was still potentially using pointers to that memory.

Changes:
- Fixed `SkwasmSurface.rasterizeToImageBitmaps` to use a synchronous
closure and handle initialization outside the stack scope.
- Hardened `withStackScope` to throw a `StateError` at runtime if the
provided closure returns a `Future`, preventing this class of bug from
reoccurring.
- Added a dedicated test suite in
`web_ui/test/skwasm/raw_memory_test.dart` to verify the safety check.

Fixes flutter#182367

incorrect usage of `withStackScope` with an `async` closure in
`SkwasmSurface.rasterizeToImageBitmaps`.

Because `withStackScope` restores the WASM linear memory stack
immediately after the closure returns, any asynchronous yields (waits)
inside the closure would cause the stack to be reclaimed while the
closure was still potentially using pointers to that memory.

Changes:
- Fixed `SkwasmSurface.rasterizeToImageBitmaps` to use a synchronous
closure and handle initialization outside the stack scope.
- Hardened `withStackScope` to throw a `StateError` at runtime if the
provided closure returns a `Future`, preventing this class of bug from
reoccurring.
- Added a dedicated test suite in
`web_ui/test/skwasm/raw_memory_test.dart` to verify the safety check.

Fixes flutter#182367
