Add TRACE_GPU_MEM tracepoints for tracking global GPU memory usage.
These are required by VSR on Android 12+ for reporting GPU driver memory
allocations.
v5:
- Drop process_mem tracking
- Set the gpu_id field to dev->primary->index (Lucas, Tvrtko)
- Formatting cleanup under 80 columns
v3:
- Use now configurable CONFIG_TRACE_GPU_MEM instead of adding a
per-driver Kconfig (Lucas)
v2:
- Use u64 as preferred by checkpatch (Tvrtko)
- Fix errors in comments/Kconfig description (Tvrtko)
- drop redundant "CONFIG" in Kconfig
