gallium: replace 16BIT_TEMPS cap with 16BIT_CONSTS

Browse Source 
All drivers that support mediump lowering should support 16BIT_TEMPS,
but some do not also want 16b consts to be lowered.  Replace the pipe
cap in preperation to remove LowerPrecisionTemporaries.

Note: also updates reference checksums for the arm64_a630_traces job,
due to lowering more to 16b
