compiler: rename {ast,hir}::BareFn* to FnPtr*

workingjubilee · fmease · workingjubilee · commit 0a4f87a14461 · 2025-07-06T15:03:08.000-07:00
Fix some comments and related types and locals where it is obvious, e.g.
- bare_fn -&gt; fn_ptr
- LifetimeBinderKind::BareFnType -&gt; LifetimeBinderKind::FnPtrType
