[AArch64] Add P{210,410}To{ARGB,AR30}Row_NEON

There 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:

              | Cortex-A55 | Cortex-A510 | Cortex-A76
P210ToARGBRow |     -59.8% |      -16.8% |     -53.2%
P210ToAR30Row |     -48.1% |      -21.8% |     -54.0%
P410ToARGBRow |     -56.5% |      -32.2% |     -54.1%
P410ToAR30Row |     -42.4% |       -4.5% |     -50.4%

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.
