Frank Barchard 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.
