Mostly just a straightforward copy of the Neon code ported to
Streaming-SVE, we can use predication to avoid needing an `Any` kernel
and use ST2 to avoid needing a separate ZIP instruction.
These is no benefit from this kernel when the SVE vector length is only
128 bits, so skip writing a non-streaming SVE implementation.

This is based on an unrolled version of the existing SVE2 code. The
implementation in this case is a pure streaming-SVE (SSVE)
implementation based on the existing SVE2 implementation, we do not use
the ZA tile.
