Squash State dirty bits to below 64. This will dramatically speed up performance on 64-bit systems due to the efficiency of angle::BitSet64. Improves performance of the GL back-end on benchmarks quite a bit. Squashes the Pack and Unpack states together. Also moves the current value dirty bits to a single dirty bit, with a separate set for each attribute. Also squashes a multisample dirty bit. Also fixes an incorrect dirty bit in StateManagerGL. We may want to implement a semi-fast version of BitSet64 for 32-bit systems if we find performance is not satisfactory.
