arm64: ssbd: Add prctl interface for per-thread mitigation
commit 9cdc0108baa8ef87c76ed834619886a46bd70cbe upstream.
If running on a system that performs dynamic SSBD mitigation, allow
userspace to request the mitigation for itself. This is implemented
as a prctl call, allowing the mitigation to be enabled or disabled at
will for this particular thread.
