Jonathan Brouwer 5964330d29 Rollup merge of #152056 - hzeller:feature-20260203-clarify-rwlock-reentrance, r=joboet
RwLock: refine documentation to emphasize non-reentrancy guarantees

This addresses the need for clarification brought up in rust-lang/rust#149693. Specifically, it notes that some implementations may choose to panic if they detect deadlock situations during recursive locking attempts for both `read()` and `write()` calls.

  * Provide an example highlighting that multiple read locks can be held across different threads simultaneously.
  * Remove the example that shows a situation that can potentially deadlock. (as demonstrated in the very same documentation a few paragraphs above)
  * Improve documentation regarding the possibility of panics during recursive read or write lock attempts.
