This reverts commit 879b5cdf.

Reason for revert: investigating a browser hang during video playback.
Reverting this CL seems to be fixing the hang. Will reland this change
with a fix to cache surfaces.

Original change's description:
> ui/gl: Ensure surface reparenting during surface destruction.
>
> When destroying a surface, it is important to also detach it from its
> parent to ensure the surface is deleted.
