[AArch64][SVE] Asm: Set SVE as unsupported feature for existing scheduler models.

Patch [4/5] in a series to add assembler/disassembler support for AArch64 SVE unpredicated ADD/SUB instructions.

We add SVE as unsupported feature for CPUs that don't have SVE to prevent errors from scheduler models saying it lacks information for these instructions.

Patch by Sander De Smalen.
