Keep optimized code out of the reference implementation. This matches
the style of the other sub calls.

This code is unused in vp9. Only vp8 still contains references to
vpx_sad_NxMx[3|8] and only for sizes 16x16, 16x8, 8x16, 8x8 and 4x4.
Remove the remaining sizes and all the highbitdepth versions.

left shifting a negative value is undefined; quiets a ubsan warning.
this is applied to a constant, no change in the generated code.

Finish the calulations in neon registers. This avoids a potentially
expensive move from neon to gp and allows at least clang to store
directly to memory.

this makes the function compatible with high-bitdepth and fixes test
failures since:

Always return an int32_t. Since it needs to be moved to a register for
shifting, this doesn't really penalize the smaller transforms.
The values could potentially be summed and shifted in place.

For the 8x8_1, the highbd output fit nicely in the existing function. 12
bit input will overflow this implementation of 16x16_1.

The function was originally written with HBD in mind. Enable it and
configure the tests.

sad neon: rewrite 32x32, add 32x16 and 32x64

sad neon: rewrite 8x8 and 8x16
sad neon: rewrite 4x4 and add 4x8
Test the _1 variant of the fdct, which simply sums the block and applies
a modifying shift based on the block size.
