1. Enable ARMv9 SVE2 and SME compilation with GCC 15 and Clang across
Android.bp, BUILD.gn, CMakeLists.txt, and linux.mk using portable
LIBYUV_SVE_ATTR, LIBYUV_SME_ATTR, and STREAMING_COMPATIBLE macros.
2. Port 46 SVE2 kernels to streaming-compatible SVE_SC functions in
row_sve.h and expose _SME entry points for processors with SME but
no non-streaming SVE2. Upgrade 15 1x SVE2 kernels to 2x unrolled,
use full-vector st1b in ARGBToRGB24Row/ARGBToRAWRow_SVE2, contiguous
ld1h/st1h in HalfFloatRow_SVE_SC, and frecpe+frecps reciprocal in
ARGBAlphaBlendRow_SVE_SC.
3. Add missing kCpuHasNEON runtime checks in planar_test.cc and define
missing HAS_*_NEON macros in row.h for existing NEON kernels.
4. Handle odd width directly in AYUVToUVRow_SVE_SC and
AYUVToVURow_SVE_SC and remove redundant width alignment guards in
AYUVToNV12 and AYUVToNV21.
5. Implement TransposeWx8_NEON for AArch64 in rotate_neon64.cc so
TransposePlane and RotatePlane90/270 cascade 16x -> 8x -> C tail.
6. Add _Any_ wrappers for 9 ARGB/float filter functions (ARGBGrayTo,
ARGBGray, ARGBSepia, ARGBColorMatrix, ARGBQuantize, ARGBShade,
GaussRow_F32, GaussCol_F32, and ARGBLumaColorTable).
7. Add HalfRow and HalfRow_16 wrappers for AVX2, NEON, SVE2, and SME
delegating to InterpolateRow{,_16} with fraction 0x80.
8. Add YUY2ToUV422Row_AVX512BW and UYVYToUV422Row_AVX512BW in
row_gcc.cc and row_win.cc.
9. Add HalfWidthRow_16To8_Odd_NEON in row_any.cc and wire into
I41xToI420 and Px10ToI420 for odd chroma widths.
10. Fix inline asm clobbers and vzeroupper placement in
TransposeWx32_16_AVX512BW and TransposeWx16_32_AVX512BW, and
re-enable 36 passing unit tests.

libyuv is an open source project that includes YUV scaling and conversion functionality.
- Scale YUV to prepare content for compression, with point, bilinear or box filter.
- Convert to YUV from webcam formats for compression.
- Convert to RGB formats for rendering/effects.
- Rotate by 90/180/270 degrees to adjust for mobile devices in portrait mode.
- Optimized for SSSE3/AVX2 on x86/x64.
- Optimized for Neon/SVE2/SME on Arm.
- Optimized for MSA on Mips.
- Optimized for RVV on RISC-V.
