Reimar Döffinger 00c916ef61 lavc/aarch64: port HEVC add_residual NEON 
Speedup is fairly small, around 1.5%, but these are fairly simple.

Reimar Döffinger 30f80d855b lavc/aarch64: port HEVC SIMD idct NEON 
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.
