Replace Host FPS with GPU command queue load ("Fifo %") (#1585)

Browse source 
* Replace Host FPS with FIFO%

* Change measurement order. Improve calculation.

Now at 100% when FIFO is blocking game exectution, rather than "0".

* Address feedback (1)

* Remove Host FPS

* FIFO rather than Fifo

* Address Ac_k feedback

* Rebase
