SurfaceTexture: add context attach & detach
This change adds the detachFromContext and attachToContext methods to
SurfaceTexture. These methods allow the SurfaceTexture to switch from
one consumer GLES context to another. This change also includes a few
cleanups to the error return codes in updateTexImage.
