This PR adds an additional help note to the ambiguity lint error output
to ask users updating their dependencies. This hopefully helps with
cases like https://github.com/rust-lang/rust/issues/149845 where newer crate versions are fixed.
Currently all core and std macros are automatically added to the prelude
via #[macro_use]. However a situation arose where we want to add a new macro
`assert_matches` but don't want to pull it into the standard prelude for
compatibility reasons. By explicitly exporting the macros found in the core and
std crates we get to decide on a per macro basis and can later add them via
the rust_20xx preludes.

error[E0308]: mismatched types
--> $DIR/macro-span-caller-replacement.rs:5:17

LL | s = format!("{arg}");
| ^^^^^^^^^^^^^^^^ expected `&str`, found `String`
...
LL | macro_with_format!();
| -------------------- in this macro invocation

= note: this error originates in the macro `format` which comes from the expansion of the macro `macro_with_format` (in Nightly builds, run with -Z macro-backtrace for more info)

Rehome 30 `tests/ui/issues/` tests to other subdirectories under `tests/ui/` [#3 of Batch #2]
Part of rust-lang/rust#133895
Methodology:
1. Refer to the previously written `tests/ui/SUMMARY.md`
2. Find an appropriate category for the test, using the original issue thread and the test contents.
3. Add the issue URL at the bottom (not at the top, as that would mess up stderr line numbers)
4. Rename the tests to make their purpose clearer
Inspired by the methodology that `@Kivooeo` was using.

Make lint `ambiguous_glob_imports` deny-by-default and report-in-deps
This pr aims to finish the second part of rust-lang/rust#114095. It converts the `ambiguous_glob_imports` lint from a warning to an error.
Currently, only the lint definition and the related tests are changed, a crater run should provide us with information on whether we should go for this.
In order to expose edition dependent divergences in some tests in the test suite, add explicit `edition` annotations. Some of these tests might require additional work to *avoid* the divergences, as they might have been unintentional. These are not exhaustive changes, purely opportunistic while looking at something else.
Emit a single error when importing a path with `_`
When encountering `use _;`, `use _::*'` or similar, do not emit two errors for that single mistake. This also side-steps the issue of resolve errors suggesting adding a crate named `_` to `Cargo.toml`.
