[M85 Migration] Ensure ProduceTexture is executed before ConsumeTexture

Black patches are seen occasionally while navigating back and
forth between pages. This is a sync issue where ConsumeTexture
gets executed before ProduceTexture's execution is completed.

To fix this issue, we add glFlush and glError before renderer
submits a frame to the browser. This will ensure that execution
of ProduceTexture is completed before ConsumeTexture is called.
