Metal embedder complains about invalid texture

[cbenhagen]

Currently when using external textures with the metal embedder we are getting a huge amount of this errors
[ERROR:flutter/shell/platform/embedder/embedder_external_texture_metal.mm(59)] External texture callback for ID 140609164393680 did not return a valid texture.

My guess is that it tries to update quicker than the video frame rate or the frame rate of the video composition. Other embedders do not treat this as an error.

The branch of flutter/plugins#3712 can be used as an example for this.
