[AArch64][SVE2] Asm: support SVE2 Accumulate Group

[c-rhodes]

Summary

Patch adds support for the following instructions:

SVE2 bitwise shift and insert:

• SRI, SLI

SVE2 bitwise shift right and accumulate:

• SSRA, USRA, SRSRA, URSRA

SVE2 complex integer add:

• CADD, SQCADD

SVE2 integer absolute difference and accumulate:

• SABA, UABA

SVE2 integer absolute difference and accumulate long:

• SABALB, SABALT, UABALB, UABALT

SVE2 integer add/subtract long with carry:

• ADCLB, ADCLT, SBCLB, SBCLT

The specification can be found here:
