Arpad Panyik 1f30ff30fb swscale: Add AArch64 Neon path for xyz12Torgb48 LE 
Add optimized Neon code path for the little endian case of the
xyz12Torgb48 function. The innermost loop processes the data in 4x2
pixel blocks using software gathers with the matrix multiplication
and clipping done by Neon.

Relative runtime of micro benchmarks after this patch on some
Cortex and Neoverse CPU cores:
