Subject: Add mutex feature for std variant

std Mutex has slightly different interface, that would require do
`.lock().unwrap()` where as `spin::Mutex` just requires `.lock()`.
This makes rather complicated to maintain `no_std` version along with
dylib with std.
Having same Mutex interface available make it easier to use and makes
sense.
