The purpose of this change is to be able to use it as a tool in docs.rs in order to provide some more stats to crates' owners. Eventually even create a badge or something along the line.

Cleanup `rmeta::MacroDef`
Avoid using rountrip parsing in the encoder and in `fn load_macro_untracked`.
The main reason I was interested in this was to remove `rustc_parse` as a dependency of `rustc_metadata` but it seems like this had other benefits as well.
Fixes#49511.

Remove spotlight
I had a few comments saying that this feature was at best misunderstood or not even used so I decided to organize a poll about on [twitter](https://twitter.com/imperioworld_/status/1232769353503956994). After 87 votes, the result is very clear: it's not useful. Considering the amount of code we have just to run it, I think it's definitely worth it to remove it.

even more clippy cleanups
* Don't pass &mut where immutable reference (&) is sufficient (clippy::unnecessary_mut_passed)
* Use more efficient &&str to String conversion (clippy::inefficient_to_string)
* Don't always eval arguments inside .expect(), use unwrap_or_else and closure. (clippy::expect_fun_call)
* Use righthand '&' instead of lefthand "ref". (clippy::toplevel_ref_arg)
* Use simple 'for i in x' loops instead of 'while let Some(i) = x.next()' loops on iterators. (clippy::while_let_on_iterator)
* Const items have by default a static lifetime, there's no need to annotate it. (clippy::redundant_static_lifetimes)
* Remove redundant patterns when matching ( x @ _ to x) (clippy::redundant_pattern)
Rename `libsyntax` to `librustc_ast`
This was the last rustc crate that wasn't following the `rustc_*` naming convention.
Follow-up to https://github.com/rust-lang/rust/pull/67763.

On the backend, rustdoc now emits `paths` entries to a crate's search
index for struct-like enum variants, and index items of type structfield
which belong to such variants point to their variant parents in the
`paths` table, rather than their enum grandparents. The path entry for
a variant is the fully qualified module path plus the enum name.
On the frontend, the search code recognizes structfields belonging to
structlike variants in the `paths` table and re-constructs the URL to
the field's anchor on the enum documentation page.

rustdoc: Fix re-exporting primitive types
* Generate links to the primitive type docs for re-exports.
* Don't ICE on cross crate primitive type re-exports.
* Make primitive type re-exports show up cross crate.
