target/arm: Implement SVE2 scatter store insns
Add decoding logic for SVE2 64-bit/32-bit scatter non-temporal
store insns.
64-bit
* STNT1B (vector plus scalar)
* STNT1H (vector plus scalar)
* STNT1W (vector plus scalar)
* STNT1D (vector plus scalar)
32-bit
* STNT1B (vector plus scalar)
* STNT1H (vector plus scalar)
* STNT1W (vector plus scalar)
