arm64: Add support for PR_SPEC_DISABLE_NOEXEC prctl() option
The PR_SPEC_DISABLE_NOEXEC option to the PR_SPEC_STORE_BYPASS prctl()
allows the SSB mitigation to be enabled only until the next execve(),
at which point the state will revert back to PR_SPEC_ENABLE and the
mitigation will be disabled.
Add support for PR_SPEC_DISABLE_NOEXEC on arm64.
