Fix `proc_macro::Ident`'s handling of `$crate`
This PR is addresses a few minor bugs, all relating to `proc_macro::Ident`'s support for `$crate`. `Ident` currently supports `$crate` (as can be seen in the `mixed-site-span` test), but:
* `proc_macro::Symbol::can_be_raw` is out of sync with `rustc_span::Symbol::can_be_raw`
* former doesn't cover `$crate` while the latter does cover `kw::DollarCrate`
* `Ident::new` rejects `$crate`
* This conflicts with the [reference definition](https://doc.rust-lang.org/nightly/reference/macros-by-example.html#r-macro.decl.meta.specifier) of `ident` which includes `$crate`.
* This also conflicts with the documentation on [`Display for Ident`](https://doc.rust-lang.org/proc_macro/struct.Ident.html#impl-Display-for-Ident) which says the output "should be losslessly convertible back into the same identifier".
This PR fixes the above issues and extends the `mixed-site-span` test to exercise these fixed code paths, as well as validating the different possible spans resolve `$crate` as expected (for both the new and old `$crate` construction code paths).

Use non-2015 edition paths in tests that do not test for their resolution2025-06-03T11:35:31+00:00Lukas Wirthlukas.wirth@ferrous-systems.com2025-06-03T08:03:42+00:00urn:sha1:eae7fe1bdb5ca2fa3c37c84c5e93d5fb3cbeab8d
This allows for testing these tests on editions other than 2015

These tests specifically test 2015 edition behavior, so ensure that they can only be run with this edition
Use `cfg_attr` AST placeholder AST `cfg_attr_trace` for diagnostics2025-05-29T10:24:23+00:00Esteban Küberesteban@kuber.com.ar2024-12-03T21:18:24+00:00urn:sha1:f80e3ac4ed1e1df2c337cbf7b231cb72ec4e3b7a
PR 138515, we insert a placeholder attribute so that checks for attributes can still know about the placement of `cfg` attributes. When we suggest removing items with `cfg_attr`s (fix Issue 56328) and make them verbose. We tweak the wording of the existing "unused `extern crate`" lint.
