[math] Split out Quat/Vector compare implementations

Browse source 
This renames existing VectorCompCompare (and quaternion equivalent) to
VectorCompCompareAll and makes VectorCompCompare produce a vector of
results with optional negation (converting 0,1 to 0,-1 for compatibility
with simd semantics).
