Makes SIMD-optimized 8x8 and 16x16 idcts for 8 and 10 bit depth
available on aarch64.
For a UHD HDR (10 bit) sample video these were consuming the most time
and this optimization reduced overall decode time from 19.4s to 16.4s,
approximately 15% speedup.
Test sample was the first 300 frames of "LG 4K HDR Demo - New York.ts",
running on Apple M1.

* commit '1bd890ad173d79e7906c5e1d06bf0a06cca4519d':
hevc: Separate adding residual to prediction from IDCT
This commit should be a noop but isn't because of the following renames:
- transform_add → add_residual
- transform_skip → dequant
- idct_4x4_luma → transform_4x4_luma
