Normalize SkXfermode_opts.h argument order as d,s[,aa].

At head they're s,d[,aa] in SkXfermode_opts.h but Sk4px::Map* expect d,s[,aa]
so we ended up having to write weird little lambda shims to match impedance.

There's no reason for these to disagree, and d,s[,aa] is the One True Order
(because no matter what you're doing in graphics, there's always a dst).

Should be no perf or image diff, though I'm suspicious it might help MSVC code generation.
