[AArch64] Add Neon impls for I{210,410}ToARGBRow_NEON

There is are existing x86 implementations for these kernels, but not for
AArch64, so add them.

Reduction in runtimes, compared to the existing C code compiled with
LLVM 17:

            | I210ToARGBRow | I410ToARGBRow
 Cortex-A55 |        -55.6% |        -56.2%
Cortex-A510 |        -22.6% |        -35.6%
 Cortex-A76 |        -48.1% |        -57.2%

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 on Arm.
  • Optimized for MSA on Mips.
  • Optimized for RVV on RISC-V.
