The existing SVE2 path only computes the average for a pair of input
values instead of groups of four as done in the Neon implementation.
The average of two values must be retained for the final odd element if
present. Existing code just handles this by falling back to the C
implementation, so mirror that for SVE2 as well.
Reduction in time taken relative to the existing Neon code, the SVE2
code remains faster even with the correct averaging:
Cortex-A510: -12.66%
Lumex C1-Nano: -6.38%
Cortex-A720: -9.73%

Add matrix and BT.601 wrapper APIs for converting ARGB to NV16 and

the planar chroma rows into the interleaved destination plane.
NV16 performs horizontal 2:1 chroma subsampling on every source row.
NV24 preserves full-resolution 4:4:4 chroma. Both paths support odd
widths, negative heights, and the existing matrix constants.
Add tests that compare scalar and optimized paths at an odd width and
height through the matrix API and its BT.601 wrapper.

android_x86 was running out registers
Using "+m" for width on __i386__ (matching the convention in
SSSE3 row functions) makes width a stack variable instead

- Implemented `I422ToRGB24Row_AVX2` and `I422ToRGB24Row_AVX512VBMI` in:
- `row_gcc.cc`: Inline assembly for GCC/Clang.
- `row_win.cc`: C++ intrinsics for MSVC (also verified with Clang).
Reduced width alignment requirement: changed from 32-pixel to 16-pixel
alignment in `convert_argb.cc` and `row_any.cc`. This allows the AVX2
path to be used for more common video resolutions.

HAS_RGBTOUVMATRIXROW_NEON is defined under
#if !defined(__GNUC__) || defined(__clang__)
to disable the NEON matrix-row path on plain GCC, where the inline asm
in ARGBToUVMatrixRow_NEON (which RGBToUVMatrixRow_NEON depends on) is
not available. However it is also defined unconditionally in the
AArch64 block, among the _I8MM defines, and is almost certainly a
copy/paste of HAS_ARGBTOUVMATRIXROW_NEON_I8MM with the suffix dropped.
On GCC/aarch64 this re-enables the call sites in convert.cc and
row_any.cc, while the definition of RGBToUVMatrixRow_NEON in
row_common.cc (guarded by HAS_ARGBTOUVMATRIXROW_NEON &&
HAS_RGB24TOARGBROW_NEON) stays disabled, producing a link failure:
convert.cc: undefined reference to 'RGBToUVMatrixRow_NEON'
row_any.cc: undefined reference to 'RGBToUVMatrixRow_NEON'
There is no RGBToUVMatrixRow_NEON_I8MM function, so the line is simply
removed rather than renamed.
