Remove unnecessary constness from ProjectionCandidate
Constness in an item bound will be represented by an effect param, so no need to record constness here.

fix: Overlapping spans in delimited meta-vars
Closes#118786
Delimited meta-vars inside of MBE's spans were set to have the same opening and closing position resulting in an ICE when debug assertions were enabled and an error was present in the templated code.
This ensures that the spans do not overlap, whilst still having the spans point at the usage of the meta-var inside the macro definition.
It includes a regression test.

More expressions correctly are marked to end with curly braces
Fixes#118859, and replaces the mentioned match statement with an exhaustive list, so that this code doesn't get overlooked in the future
skip rpit constraint checker if borrowck return type error
Fixes#117794Fixes#117886Fixes#119025
Prior to change #117418, the value of `concrete_opaque_types` for `mir_borrock(T:🅰️:opaque)` was `None`. However, due to modifications in `body.local_decls`, the return value had been changed.
The changed of `body.local_decls` has let to the addition of `ty:Error` to `infcx.opaque_type_storage.opaque_types` during `TypeChecker::equate_inputs_and_outputs`. This is due to it utilizing the output of a function signature that was appended during `construct_error`(which previously only appended a `ty::Error`) and then execute `TypeChecker::Related_types`.
Therefore, in this PR, I've implemented a condition to bypass the rpit check when an error is encountered.

Don't pass lint back out of lint decorator
Change the decorator function in the signature of the `emit_lint`/`span_lint`/etc family of methods from `impl for<'a, 'b> FnOnce(&'b mut DiagnosticBuilder<'a, ()>) -> &'b mut DiagnosticBuilder<'a, ()>` to `impl for<'a, 'b> FnOnce(&'b mut DiagnosticBuilder<'a, ()>)`. I consider it easier to read this way, especially when there's control flow involved.

Collect lang items from AST, get rid of `GenericBound::LangItemTrait`
r? `@cjgillot`
cc #115178
Looking forward, the work to remove `QPath::LangItem` will also be significantly more difficult, but I plan on doing it as well. Specifically, we have to change:
1. A lot of `rustc_ast_lowering` for things like expr `..`
2. A lot of astconv, since we actually instantiate lang and non-lang paths quite differently.
3. A ton of diagnostics and clippy lints that are special-cased via `QPath::LangItem`
Meanwhile, it was pretty easy to remove `GenericBound::LangItemTrait`, so I just did that here.
