George Steed 949cb623bf Add SVE2 and SME implementations of I444ToRGB24Row
Move the READYUV444_SVE_2X and I444TORGB_SVE_2X macros to row_sve.h so
they are usable in both SVE2 and SME implementations, and use them to
add new I444ToRGB24Row implementations for SVE2 and SME. We need to use
the unrolled versions here to use the ST3B interleaving store
instructions, since there is no partial vector version of this store
instruction.

Reduction in time taken observed for the new SVE2 implementation,
compared to the existing Neon implementation:

Cortex-A510: -57.6%
Cortex-A520: -38.1%
Cortex-A710: -15.5%
Cortex-A715:  -9.2%
Cortex-A720:  -9.2%
  Cortex-X2: -25.8%
  Cortex-X3: -26.2%
  Cortex-X4: -23.2%
Cortex-X925: -17.8%
