Restore old NEON blit_mask_d32_a8 methods.

As you'll see from the BUG line, we have a strong indication that the new Sk4px
methods regress some devices.  This restores the old code back as literally as possible
while still fitting in SkOpts framework.

This is ideally temporary breathing room.

We should get an early indication of if those bugs will improve by watching https://perf.skia.org/#4004
