lavc/hevc: move subs earlier in qpel uni-weighted NEON loops
Move the subs instruction before the store macro in the 8x-unrolled
loops of qpel_uni_w_v4/v8/v16/v64 and qpel_uni_w_hv4/hv8/hv16, so
that many NEON instructions from the store macro separate it from the
conditional branch. This gives the CPU pipeline time to resolve the
condition flags before the branch decision.

lavc/hevc: add aarch64 NEON for qpel uni-weighted vertical filter
Add NEON-optimized implementations for HEVC QPEL uni-weighted
vertical interpolation (put_hevc_qpel_uni_w_v) at 8-bit depth.

These functions perform weighted uni-directional prediction with
vertical QPEL filtering:
- 8-tap vertical QPEL filter
- Weighted prediction: (filter_result * wx + offset) >> shift

Previously only sizes 4, 8, 16, 64 were optimized. This patch adds
optimized implementations for all remaining sizes: 6, 12, 24, 32, 48.

Performance results on Apple M4:
./tests/checkasm/checkasm --test=hevc_pel --bench

put_hevc_qpel_uni_w_v6_8_neon:   3.40x
put_hevc_qpel_uni_w_v12_8_neon:  3.24x
put_hevc_qpel_uni_w_v24_8_neon:  3.06x
put_hevc_qpel_uni_w_v32_8_neon:  2.66x

lavc/hevc: add aarch64 NEON for qpel uni-weighted HV filter
Add NEON-optimized implementations for HEVC QPEL uni-directional
weighted HV interpolation (put_hevc_qpel_uni_w_hv) at 8-bit depth,
for block widths 6, 12, 24, and 48.

These functions perform horizontal then vertical 8-tap QPEL filtering
with weighting (wx, ox, denom) and output to uint8_t. Previously
only widths 4, 8, 16, 32, 64 were implemented; this completes
coverage for all standard HEVC block widths.

Performance results on Apple M4:
./tests/checkasm/checkasm --test=hevc_pel --bench

put_hevc_qpel_uni_w_hv6_8_neon:   3.11x
put_hevc_qpel_uni_w_hv12_8_neon:  3.19x

lavc/hevc: add aarch64 NEON for epel uni horizontal filter
Add NEON-optimized implementations for HEVC EPEL uni-directional
horizontal interpolation (put_hevc_epel_uni_h) at 8-bit depth.

These functions perform horizontal 4-tap EPEL filtering with
output directly to uint8_t pixels (no weighting):
- 4-tap horizontal EPEL filter
- Output: (filter_result + 32) >> 6, clipped to [0, 255]

Supports all block widths: 4, 6, 8, 12, 16, 24, 32, 48, 64.

lavc/hevc: reorder aarch64 NEON pel function assignments
Group assignments by filter family (qpel, epel), variant
(base, uni, bi, uni_w, bi_w) and direction (pixels, h, v, hv).
Add NEON8_FNASSIGN_QPEL_H macro to replace repeated manual
qpel horizontal assignments.

No functional change.
