Rollup merge of #116172 - joboet:recursive_tls_initialization, r=dtolnay
Broaden the consequences of recursive TLS initialization This PR updates the documentation of `LocalKey` to clearly disallow the behaviour described in [this comment](https://github.com/rust-lang/rust/issues/110897#issuecomment-1525738849). This allows using `OnceCell` for the lazy initialization of TLS variables, which panics on reentrant initialization instead of updating the value like TLS variables currently do. ``@rustbot`` label +T-libs-api r? ``@m-ou-se``
