Remove ruy's dependency on the gemmlowp profiler.

Introduce the 'ruy profiler', a more modern descendent of it (pure C++11, correct, tested including under TSan, more useful features including formatted parametrized labels and better reporting of multi-thread profiles, treeview-manipulation API, more documentation, more accurate).

Port ruy to using the ruy profiler (TFLite should follow). Add per-GEMM-shape profiling labels, now very easy thanks to formatted parametrized labels, previously too cumbersome to do to be submitted so we had to keep unsubmitted patches for that common profiling need.
