sw_scale: Add specializations for hscale 16 to 19
Provide arm64 neon optimized implementations for hscale16To19 with
filter sizes 4, 8 and X4.
The tests and benchmarks run on AWS Graviton 2 instances.
The results from a checkasm tool are shown below.

(Note, the checkasm tests for these functions haven't been
merged since they fail on x86.)
