Frank Barchard ee99b85126 Port ARGBToRGB565 from aarch64 neon to 32 bit 
The 64 bit version of ARGBToRGB565 to 32 bit. 64 bit is using sri which shifts and inserts, saving some masking.  The instruction is available for neon 32 bit as well.

  • Scale YUV to prepare content for compression, with point, bilinear or box filter.
  • Convert to YUV from webcam formats.
  • Convert from YUV to formats for rendering/effects.
  • Rotate by 90/180/270 degrees to adjust for mobile devices in portrait mode.
  • Optimized for SSE2/SSSE3/AVX2 on x86/x64.
  • Optimized for Neon on Arm.
  • Optimized for DSP R2 on Mips.
