Fix query management in GpuProfiler
GL query objects were being used incorrectly in GpuProfiler across GL
context resets, which could cause endless creation of additional GL
query objects.
Have the compositor notify the GpuProfiler when the GL context is
created and destroyed, so it can reset its state appropriately.
Also impose a limit of 32 outstanding queries to help prevent endless
query object creation in the future. If we hit the limit we print a log,
reset everything, and start over.
Bug: 34256609
Test: Manually tested that: (a) we no longer get GL errors after
glGetQueryObjectiv() calls after a context destroy/create cycle, and (b)
the queue overflow handling works as expected.
