gallium/u_threaded: Add some atrace/perfetto

Browse source 
Use the MESA_TRACE_BEGIN/END() macros which will generate perfetto
traces (if perfetto is enabled) otherwise atrace (if android build), in
either case creating track events which will show up on the frontend
thread in a perfetto trace, giving visibility into where syncs happen.
