Title: cc: Avoid issuing COMMANDS_COMPLETED queries unless necessary.

Minor change to the Fence API that allows GLRenderer to not
issue sync queries unless some resource that depend on them
was used to produce a frame.

Also includes some minor renaming cleanup related to usage of
Fences in ResourceProvider code.
