anv: Add statistic for 'GRF registers' for Xe3+

Browse source 
For Xe3+ the registers are tightly packed to make better use of GRF
space, so add a statistic to keep track of how many registers were used.
For previous versions this is not useful since the code is spreading
the registers among the whole space.
