Description
PyMutex is a poisoning mutex. That means it has to check at runtime if the current thread is panicking. There is no way to do this in no_std. The current implementation of PyMutex cannot be supported without std.
I think we should add a non-poisoning variant, update the critical section API to accept either variant, and feature-gate the poisoning variant.

Research direction
Start by locating the current PyMutex implementation and the critical section API. Read how poisoning and std dependencies are handled, then determine the changes needed for a non-poisoning variant and feature-gated poisoning support; done means the API supports no_std without requiring std.
