  [WebGL] Abstract querying of drawing buffer texture target
https://bugs.webkit.org/show_bug.cgi?id=256944
rdar://problem/109495048

Reviewed by Kimmo Kinnunen.

Move the interface for querying external image texture target and binding point
to GraphicsContextGL so that it can be implemented by
RemoteGraphicsContextGLProxy. Since the texture target and binding point don't
change, instead of adding a new remote message the remote proxy stores cached
versions sent on creation of the RemoteGraphicsContextGL.

Support work for WebXR with GPUP.
