Mostly just straightforward copies of the Neon code ported to
Streaming-SVE, these follow the same pattern as the prior ScaleRowDown2
SME kernels, but operating on 16-bit data rather than 8-bit.
These is no benefit from this kernel when the SVE vector length is only
128 bits, so skip writing a non-streaming SVE implementation.

There is no benefit from an SVE version of this kernel for devices with
an SVE vector length of 128-bits, so skip directly to SME instead. We do
not use the ZA tile here, so this is a purely streaming-SVE (SSVE)
implementation.
