Delete RenderEngine unused code

* V0 skia implementation beat the prior change deleting unused code, so
delete bindExternalTextureBuffer there.
* Remove useNativeFenceSync, now that there's no more usages
* Remove impl::RenderEngine, since there's no need for a private
impl-superclass spanning every RenderEngine implementation
* Clean up mock/RenderEngine
