This removes the code in Gecko that was only allowing opaque
compositor surfaces, now that the underlying work in WR and
SWGL to support these is complete.

It's a little difficult to tell with the unrelated intermittents, but I think the only remaining test failures are in Win10 SW-WR (see R4 on Win10 in [1]).

It looks like those two canvas tests draw correctly in the test, but then the reference is a blank output and the text remains. Lee, any ideas what might cause that?
