Remove disable_direct_composition GPU workaround

The only workaround entry is for a bug that's likely related to video
overlays rather than direct composition as a whole. The other linked
bug doesn't even seem related to direct composition.

However, we still need to disable direct composition for things like
RenderDoc so (re)introduce the --disable-direct-composition command
line flag.
