target/arm: Implement MVE VCADD
Implement the MVE VCADD insn, which performs a complex add with
rotate. Note that the size=0b11 encoding is VSBC.
The architecture grants some leeway for the "destination and Vm
source overlap" case for the size MO_32 case, but we choose not to
make use of it, instead always calculating all 16 bytes worth of
results before setting the destination register.
