arm64/fpsimd: Sync FPSIMD state with SVE for SME only systems

Browse source

Currently we guard FPSIMD/SVE state conversions with a check for the system
supporting SVE but SME only systems may need to sync streaming mode SVE
state so add a check for SME support too.  These functions are only used
by the ptrace code.
