Fix texture corruption on Windows

[cbracken]

Notify Skia that we've updated texture handles within the current
binding such that Skia invalidates any assumptions about previous
context modifications that it had made.

This fixes a texture corruption issue reported in
flutter/flutter#78648

@chinmaygarde any suggestions for testing this? Will take a look at #16711 for ideas in the meantime.

any suggestions for testing this

The embedder harness is not suited for verifying OpenGL state. You could manually check bindings but that would involve writing OpenGL directly in backend agnostic harness.

[chinmaygarde]

Spoke via chat. We are going to forego the context reset on the destruction callback because of lifecycle issues and document that embedder may not trample OpenGL state in the destructor. This is hard to do during texture creation so the reset during that callback will be kept in place. This should fix the reported issue.
