st/mesa: ask pipe driver to recreate derived internal resources when (re-)binding external textures

Use the resource_changed callback to invalidate internal resources
derived from 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.
