Turn on more of the platform_canvas_unittests

Most of the TranslateLayer test can pass even on AURA machines; only
one clause needs to be #ifdef'd out on MACOS *and* AURA.

Also documents the surpising DstATop xfermode use in MakeOpaque,
and changes that function from OS_WIN-only to running on every platform,
where it should be a cheap noop.

Followup: other parts of the Chrome codebase have their own
MakeOpaque implementations; we can probably share this through
skia_utils.
