Refactor 4f gradients using trait templates
Some 4f gradient housekeeping.
1) replace <DstPtrType, ColorProfile> specialization tuples with an enum covering all dest types
(L32, S32, F16, F32)
2) group various template helpers into dest trait classes, specialized for each dest type
(2a - conflate current dst_swizzle and scale_for_dest ops into one load op)
