Auto merge of #60669 - c410-f3r:attrs-fn, r=petrochenkov
Allow attributes in formal function parameters Implements https://github.com/rust-lang/rust/issues/60406. This is my first contribution to the compiler and since this is a large and complex project, I am not fully aware of the consequences of the changes I have made. **TODO** - [x] Forbid some built-in attributes. - [x] Expand cfg/cfg_attr
