Use macros for sk_Caps again.
This undoes the change from http://review.skia.org/400541 and reworks
sk_Caps to use macros, exactly like the existing CPPCodeGenerator.
This compromise is necessary for when-expressions. Specifically, when-
expressions must be valid when parsed *either* as SkSL or as C++. We
want to support when-expressions that reference sk_Caps, like:
layout(when=!sk_Caps.floatIs32Bits)
The macro approach allows this when-expression to work.
