Addresses issues raised in the review of PR #24518 and includes changes to 17 tests' metadata for those that now PASS.

Contains fixes in PR #24518:

Updated the offscreen canvas rendering context to use the offscreen canvas' size. This involved upgrading several methods to accept u64 sizes.

Additionally, the code in OffscreenCanvas::SetWidth() and OffscreenCanvas::SetHeight() was updated to send CanvasMsg::Recreate to the canvas paint thread.
