docs(LocalKey<T>): clarify that T's Drop shouldn't panic Clarify that should a TLS destructor panics, the process will abort. Also, an abort may be obfuscated as the process can be terminated with `SIGSEGV` or [`STATUS_STACK_BUFFER_OVERRUN`](https://devblogs.microsoft.com/oldnewthing/20190108-00/?p=100655) (i.e., `SIGABRT` is not guaranteed), so explicitly prints that the process was aborted.
