suggest iter_mut() where trying to modify elements from .iter()

Fix incorrect mutable suggestion information for binding in ref pattern like:  `let &b = a;`

fixes rust-lang#114896

I find we have to get pat_span but not local_decl.source_info.span for suggestion. In `let &b = a;`  pat_span is &b. I think check `let &b = a` in hir to make sure it is hir::Node::Local(hir::Local {pat: hir::Pat{kind: hir::PatKind::Ref(.......   can distinguish it from other situation, but I'm not sure.

If my processing method is not accurate, please guide me to modify it, thank you.

fix homogeneous_aggregate not ignoring some ZST

This is an ABI-breaking change, because it fixes bugs in our ABI code. I'm not sure what that means for this PR, we don't really have a process for such changes, do we? I can only hope nobody relied on the old buggy behavior.

Call `LateLintPass::check_attribute` from `with_lint_attrs`

Fixes rust-lang#115571

For regular `register_late_pass` lints also means that `last_node_with_lint_attrs` is correct when in `check_attribute`, I've added a test that previously failed for `clippy::allow_attributes`

As far as I can see the only late lint in rustc that uses `check_attribute` is `unstable_features` which is allow by default and deprecated so this is mostly for clippy (or future rustc lints)

Point out if a local trait has no implementations

Slightly helps with rust-lang#115741

Improve diagnostic for generic params from outer items (E0401)

Generalize the wording of E0401 to talk about *outer items* instead of *outer functions* since the current phrasing is outdated. The outer item can be a function, constant, trait, ADT or impl block (see the new UI test for the more exotic examples).

Further, don't suggest introducing generic parameters to constant items unless the feature `generic_const_items` is enabled.

Lastly, make E0401 translatable while we're at it.

Fixes rust-lang#115720.
