700f153cb8 [libyuv] Add Qualcomm Hexagon HVX SIMD support 
Implement Qualcomm Hexagon Vector Extensions (HVX) 128-byte SIMD
optimizations and runtime CPU detection for Hexagon DSP targets:
- CPU detection: Add kCpuHasHexagon and kCpuHasHVX flags,
  LIBYUV_DISABLE_HVX environment variable support, and Hexagon
  unit_test mmap/munmap shims.
- Rotate/Transpose (rotate_hvx.cc): Implement TransposeWxH_HVX,
  TransposeUVWxH_HVX, TransposeWxH_16_HVX, and TransposeWxH_32_HVX
  using power-of-2 vdeal/vshuff butterfly networks.
- Compare (compare_hvx.cc): Implement HammingDistance_HVX,
  SumSquareError_HVX, HashDjb2_HVX, and Ssim4x4Row_HVX.
- Scale (scale_hvx.cc): Implement 16 scale row kernels including
  ScaleAddRow_HVX, ScaleRowDown2*_HVX (8-bit and 16-bit),
  ScaleRowDown4*_HVX, ScaleARGBRowDown2*_HVX, and
  ScaleUVRowDown2*_HVX.
- Row functions (row_hvx.cc): Implement 58 row kernels covering
  copy/set/mirror, split/merge, 8/16-bit conversions, YUV-to-ARGB,
  ARGB-to-YUV, ARGB channel swizzles, blend, attenuate, and
  interpolate using hardware-predicated partial loads/stores.

eeb06a6451 [libyuv] Optimize ARGBRotate for Intel SSE2, AVX2, and AVX-512 
Optimize 32-bit ARGBRotate (0, 90, 180, 270) across Intel x86/x64
architectures (SSE2, AVX2, AVX512BW), with matching kernels for ARM
(NEON, SVE2, SME), WASM, LoongArch (LSX, LASX), and RISC-V (RVV):

- Replace column-by-column ScaleARGBRowDownEven gather loops in
  ARGBTranspose (90/270) with full-plane horizontal tile transposes:
  - AVX512BW (TransposeWxH_32_AVX512BW / TransposeNx4_32_AVX512BW):
    Transpose 16x16 blocks across zmm0..zmm31 using 4-stage
    vpunpckldq/hdq, vpunpcklqdq/hqdq, and vshufi32x4 butterflies with
    k-masked right and bottom tails, eliminating Any wrappers and scalar
    C edge fallbacks.
  - AVX2 (TransposeWxH_32_AVX2 / TransposeNx4_32_AVX2):
    Transpose 8x8 blocks across ymm0..ymm15 using vpunpck* and
    vperm2i128 with vpmaskmovd masked tails.
  - SSE2 (Transpose4x4_32_SSE2 / Transpose4x4_32_Any_SSE2):
    Transpose 4x4 blocks in xmm registers.
- Implement ARGBRotate180 directly via ARGBMirror with negative height,
  avoiding intermediate row buffer allocations and extra copies.
- Implement ARGBRotate0 via ARGBCopy.

Speedup vs Before (1275x1650, US Letter 150 DPI, 1000 iterations):
CPU                  | 0 deg   | 90 deg  | 180 deg | 270 deg
---------------------|---------|---------|---------|--------
Intel Ice Lake       | 1.02x   | 1.34x   | 1.18x   | 1.33x
Intel Skylake-X      | 1.02x   | 1.20x   | 1.07x   | 1.13x
Intel Emerald Rapids | 1.01x   | 1.07x   | 1.00x   | 1.07x
Intel AVX-512 vs C   | 1.00x   | 2.67x   | 2.41x   | 2.63x
