avcodec/x86/vvc/of: Avoid jump
At the end of the height==8 codepath, a jump to RET at the end
of the height==16 codepath is performed. Yet the epilogue
is so cheap on Unix64 that this jump is not worthwhile.
For Win64 meanwhile, one can still avoid jumps, because
for width 16 >8bpp and width 8 8bpp content a jump is performed
to the end of the height==8 position, immediately followed
by a jump to RET. These two jumps can be combined into one.
