f4bd4434c4 glsyncmeta: separate out gpu/cpu waits.
CPU waits are more expensive and are only required if the CPU is ever going to
access the data. GPU waits perform inter-context synchronisation and are cheaper
as they don't require CPU intervention.

0e404ae3fc glsyncmeta: add vfuncs for all operations
there could be other ways/requirements for synchronising two GPU command
streams (whether GL or platform specific).

e.g. glfencesync/eglwaitnative/cond/etc

6bb113f685 gl: add a sync meta for synchronizing across GL contexts
A context can create a GLsync object that can be waited on in order
to ensure that GL resources created in one context are able to be
used in another shared context without any chance of reading invalid
data.

This meta would be placed on buffers that are known to cross from
one context to another.  The receiving element would then wait
on the sync object to ensure that the data to be used is complete.
