Implement highQualityFilter16 so GM doesn't crash when you give it resources.

Implement highQualityFilter16 so GM doesn't crash when you give it resources.

Testing consisted of:
 1) ninja -C out/Debug gm && gm -i resources --match mandrill_512 -w /tmp/gm
 2) notice that gm didn't segfault
 3) look in /tmp/gm and see a bunch of handsome monkeys

src/core/SkBitmapFilter.cpp:87: highQualityFilter(&SkPackARGB32, s, x, y,
colors, count);
Have we confirmed that SkPackARGB32 got inlined (same with PackTo565? I presume
so, but just want to make sure.

LGTM as long as there are no performance gotchas here.
