Integrates the GLProfiler into GLQueueRunner to provide GPU timestamp
profiling for OpenGL render passes, similar to the Vulkan backend.
Profiled operations:
- RenderPass (with tag name for identification)
- Copy operations
- Blit operations
- Readback operations
- ReadbackImage operations
The profiler is initialized in CreateDeviceObjects() and shutdown in
DestroyDeviceObjects(). Timing results are logged each frame when the
GPU profile debug overlay is enabled.
