skia: Fix -Wextra-semi warnings in non-dcheck builds.

Use SkDEBUGCODE(...;) instead of SkDEBUGCODE(...);

clang-format has trouble formatting the new spelling, but
it's already commonly used in skia, and if you have something
SkDEBUGCODE instead of just checking `#if SK_DEBUG` then
there isn't all that much you can do.

(You could make SkDEBUGCODE() insert a static_assert(true, "")
at the end to eat semicolons after it, but that's also
a bit gross. And many SkDEBUGCODE()s already put the ; inside
the parens.)
