Re-enables accelerated compositing for background extensions. Background extensions only attempt to create a GL context if needed (e.g. they create a visible view) so this change has no effect on extensions without visible presence.
Tested by:
1. Adding a few extensions without visible presence to my profile
2. Tracing startup to make sure that no GL contexts are created
3. Verified that the GPU process size does not change when enabling / disabling the extensions
