arm64: ptrace: Use ARM64_SME to guard the SME register enumerations

commit eb9a85261e upstream.

We currently guard REGSET_{SSVE, ZA} using ARM64_SVE for no good reason.
Both enumerations would be pointless without ARM64_SME and create two empty
entries in aarch64_regsets[] which would then become part of a process's
native regset view (they should be ignored though).

Switch to use ARM64_SME instead.
