With rust-lang#103360 having landed, I don't think we still need this `GetFileInformationByHandleEx` shim.

Improve miri_print_borrow_stacks

Per post-merge review on rust-lang/miri#2322

* `miri_print_stacks` renamed to `miri_print_borrow_stacks`
* A bit more details in docs, clarified how unstable these functions are meant to be
* Print an `unknown_bottom` if one exists

Open question: Currently `miri_get_alloc_id` gets the expected `AllocId` for `Wildcard` pointers, but for pointers with no provenance, the function reports UB and halts the interpreter. That's definitely wrong. But what _should_ we do? Is it reasonable to check if the pointer has `None` provenance and try to get an `AllocId` for its address? That still leaves us with a failure path, which in this case might be best-handled as an ICE? I'm just not sure that changing the return type of `miri_get_alloc_id` to `Option` is a win because it complicates all normal uses of this.
add pthread_getname_np

A new libstd test needs this, and there doesn't seem to be a good reason not to have this.
