Rollup merge of #143069 - jsimmons:current-thread-id-accessor, r=joshtriplett,tgross35
Add fast-path for accessing the current thread id Accessing the thread id is often used in profiling and debugging, as well as some approaches for sound single-threaded access to shared data. Currently the only way to access the thread id is by first obtaining a handle to the current thread. While this is not exactly slow, it does require an atomic inc-ref and dec-ref operation, as well as the injection of `Thread`'s drop code into the caller. This publicly exposes the existing fast-path for accessing the current thread id. edit: ACP: https://github.com/rust-lang/libs-team/issues/650
