Use the invalidate_resource pipe callback to invalidate external
textures when they are (re-)bound. This is needed to comply with the
requirement from the GL_OES_EGL_image_external extension that a call
to glBindTexture guarantees that all further sampling will return
values that correspond to the values in the external texture at or
after the time that glBindTexture was called.
