[AArch64] Add SVE2 implementation of RGB24ToARGBRow

Browse Source 
This can make use of the existing helper functions for RAWToARGBRow_SVE2
and RAWToRGBARow_SVE2 since the layouts are similar, we just need to
adjust the TBL constants to match the different input layout.

Observed reduction in runtime compared to the existing Neon kernel:

Cortex-A510: -25.6%
Cortex-A720: -15.2%
  Cortex-X2: -10.2%
  Cortex-X4: -30.2%
