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

mainline inclusion
from mainline-v6.2-rc4
commit eb9a8526
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I8E73O
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=eb9a85261e297292c4cc44b628c1373c996cedc2



-------------------------------------------------

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.
