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 `std::mem::{size_of, size_of_val, align_of, align_of_val}` from the
prelude instead of importing or qualifying them.
These functions were added to all preludes in Rust 1.80.
