be09427b11 Rollup merge of #61813 - matthewjasper:remove-unnecessary-symbol-ops, r=petrochenkov 
Remove some unnecessary symbol interner ops

* Don't gensym symbols that don't need to worry about colliding with other symbols
* Use symbol constants instead of interning string literals in a few places.
* Don't generate a module in `__register_diagnostic`

3f511ade5b 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

58c68d00fd Pass symbols to ExtCtxt::std_path instead of strings. 
Because this function is hot.

Also remove the dead `ty_option` function.

Add match arm scopes and other scope fixes

* Add some previously missing fake borrows for matches.
