In P010ToARGBMatrixFilterOverflow, P210ToARGBMatrixFilterOverflow,
P010ToAR30MatrixFilterOverflow, and P210ToAR30MatrixFilterOverflow,
the tests set src_stride_uv to width (1039) and allocated
width * src_uv_height elements. For odd widths, the interleaved UV
row requires (width + 1) & ~1 elements (1040). Using width for the
stride and buffer size caused the second row to read past the allocated
buffer and access uninitialized memory under MSan.
Fix this by computing src_stride_uv = (width + 1) & ~1 and sizing the
allocated buffer to src_stride_uv * src_uv_height.
In TestI400LargeSize, the test attempts large allocations totaling
over 10 GB (~2 GB for source and ~8.5 GB for destination). Under
MemorySanitizer (MSan), large allocations can exceed shadow memory
virtual address limits or assert. Skip this test under MSan by checking
__SANITIZE_MEMORY__ and __has_feature(memory_sanitizer).

Adds RGBToYMatrixRow_AVX2 which reads 24 bit RGB values by reading 3 vectors instead of 4 and permutes them into 4 ARGB vectors before conversion.
Also adds RGBToYMatrixRow_Opt and RGBToYMatrixRow_2Step_Opt to convert_argb_test.cc to benchmark and compare the direct AVX2 conversion vs a 2-step approach.

implementing horizontal paired adds and accumulation to improve
performance on SiFive x280, and fixes the remainder logic to use valid
vlseg4 loads. Adds TestARGBToUVRow_Any to test odd-width remainder
handling.
Also fixes a build break for non-RVV compilations by ensuring all RVV
functions and their closing cplusplus braces are correctly wrapped in
#if !defined(LIBYUV_DISABLE_RVV).
Also adds NV12ToNV21 as a macro alias for NV21ToNV12 in
planar_functions.h, as the conversion is bidirectional (swapping byte
pairs in the interleaved chroma plane). (Patch from
