George Steed 5bac99fe09 [AArch64] Rework data loading in ScaleARGBFilterCols_NEON 
The existing code makes use of lane-indexed LD2 instructions to load the
input data however this creates a strong dependency chain between
consecutive load instructions. We can reduce this dependency chain by
instead loading two vectors with wider lane-indexed LD1 instructions and
then performing a permute to unzip the data.

We can also avoid the need for a complex sequence of DUP + EXT
instructions by using TBL to permute the data exactly as we want it.

Reduction in runtimes observed compared to the existing Neon
implementation:

 Cortex-A55:  =0.0%
Cortex-A510: -44.2%
Cortex-A520: -47.6%
 Cortex-A76: -45.8%
Cortex-A715: -58.3%
Cortex-A720: -58.4%
  Cortex-X1: -66.7%
  Cortex-X2: -68.0%
  Cortex-X3: -67.9%
  Cortex-X4: -70.0%
