Substitutes c->v_loop_filter_chroma_intra and c->h_loop_filter_chroma_intra
with daedalus wrappers in the bit_depth=8 / chroma_format_idc<=1 (4:2:0)
branch. 4:2:2 stays on the in-tree NEON path (the daedalus chroma intra
dispatch is 4:2:0-only).
The fourier dispatches were exposed in PR #11 (DEFINE_INTRA_DISPATCH
macro generates the public daedalus_dispatch_h264_deblock_chroma_*_intra
symbols + recipe wrappers).
Re-architects the chroma init: v_loop_filter_chroma_intra was previously
assigned unconditionally to the NEON variant (which works for both 4:2:0
and 4:2:2). We now assign it INSIDE both branches of the chroma_format_idc
conditional — 4:2:0 picks daedalus, 4:2:2 keeps NEON. No regression for
4:2:2 streams.
Same NEON-to-NEON via recipe shape as 0010 luma intra.
Closes the deblock substitution layer for the 4:2:0 / 8-bit hot path:
- 0005 luma_v non-intra ✓
- 0008 luma_h non-intra ✓
- 0009 chroma_v / chroma_h non-intra ✓
- 0010 luma_v / luma_h intra ✓
- 0013 chroma_v / chroma_h intra ✓
All 8 deblock variants for the common 4:2:0 path now route through
daedalus. 4:2:2 chroma + the chroma422 mbaff variants stay on in-tree
NEON.
Verified the patch applies cleanly on top of 0001-0012 against the
pinned upstream commit b57fbbe5 on hertz.
