lints: add improper_ctypes_definitions 
This commit adds a new lint - `improper_ctypes_definitions` - which
functions identically to `improper_ctypes`, but on `extern "C" fn`
definitions (as opposed to `improper_ctypes`'s `extern "C" {}`
declarations).

d45ce5aed6 Inline catching panics into std::catch_unwind 
This allows LLVM to inline the happy path, such that catching unwinding is
zero-cost when no panic occurs. This also allows us to match the code generated
by C++ try/catch.

Rollup merge of #66766 - RalfJung:panic-comments, r=SimonSapin 
Panic machinery comments and tweaks

This is mostly more comments, but I also renamed some things:
* `BoxMeUp::box_me_up` is not terribly descriptive, and since this is a "take"-style method (the argument is `&mut self` but the return type is fully owned, even though you can't tell from the type) I chose a name involving "take".
* `continue_panic_fmt` was very confusing as it was entirely unclear what was being continued -- for some time I thought "continue" might be the same as "resume" for a panic, but that's something entirely different. So I renamed this to `begin_panic_handler`, matching the `begin_panic*` theme of the other entry points.
