rustdoc: don't ignore path distance for doc aliases

Ran into a bit of an issue due to the overloading of space (it needs to be a metachar for most searches, but not for doc aliases that have space in them).  Not sure if I need to also need to account for other whitespace chars.

rustdoc search: prefer stable items in search results

fixes https://github.com/rust-lang/rust/issues/138067

this does add a new field to the search index, but since we're only listing unstable items instead of adding a boolean flag to every item, it should only increase the search index size of sysroot crates, since those are the only ones using the `staged_api` feature, at least as far as the rust project is concerned.

rustdoc-search: handle `impl Into<X>` better

This PR fixes two bugs I ran into while searching the compiler docs:

- It omitted an `impl Trait` entry in the type signature field, producing `TyCtxt, , Symbol -> bool`
- It didn't let me search for `TyCtxt, DefId, Symbol -> bool` even though that's a perfectly good description of the function I was looking for (the function actually used `impl Into<DefId>`

86da4be47f rustdoc: use a trie for name-based search 
Preview and profiler results
----------------------------

Here's some quick profiling in Firefox done on the rust compiler docs:

- Before: https://share.firefox.dev/3UPm3M8
- After: https://share.firefox.dev/40LXvYb

Here's the results for the node.js profiler:

- https://notriddle.com/rustdoc-html-demo-15/trie-perf/index.html

Here's a copy that you can use to try it out. Compare it with [the nightly].
Try typing `typecheckercontext` one character at a time, slowly.

- https://notriddle.com/rustdoc-html-demo-15/compiler-doc-trie/index.html

[the nightly]: https://doc.rust-lang.org/nightly/nightly-rustc/

The fuzzy match algo is based on [Fast String Correction with
Levenshtein-Automata] and the corresponding implementation code in [moman]
and [Lucene]; the bit-packing representation comes from Lucene, but the
actual matcher is more based on `fsc.py`. As suggested in the paper, a
trie is used to represent the FSA dictionary.

The same trie is used for prefix matching. Substring matching is done with a
side table of three-character[^1] windows that point into the trie.

[Fast String Correction with Levenshtein-Automata]: https://github.com/tpn/pdfs/blob/master/Fast%20String%20Correction%20with%20Levenshtein-Automata%20(2002)%20(10.1.1.16.652).pdf
[Lucene]: https://fossies.org/linux/lucene/lucene/core/src/java/org/apache/lucene/util/automaton/Lev1TParametricDescription.java
[moman]: https://gitlab.com/notriddle/moman-rustdoc

User-visible changes
--------------------

I don't expect anybody to notice anything, but it does cause two changes:

- Substring matches, in the middle of a name, only apply if there's three
  or more characters in the search query.
- Levenshtein distance limit now maxes out at two. In the old version,
  the limit was w/3, so you could get looser matches for queries with
  9 or more characters[^1] in them.

[^1]: technically utf-16 code units

12dc24f460 rustdoc-search: simplify rules for generics and type params 
This commit is a response to feedback on the displayed type
signatures results, by making generics act stricter.

Generics are tightened by making order significant. This means
`Vec<Allocator>` now matches only with a true vector of allocators,
instead of matching the second type param. It also makes unboxing
within generics stricter, so `Result<A, B>` only matches if `B`
is in the error type and `A` is in the success type. The top level
of the function search is unaffected.

f36c5af359 rustdoc-search: single result for items with multiple paths 
This change uses the same "exact" paths as trait implementors
and type alias inlining to track items with multiple
reachable paths. This way, if you search for `vec`, you get
only the `std` exports of it, and not the one from `alloc`.

It still includes all the items in the search index so that
you can search for them by all available paths. For example,
try `core::option` and `std::option`, and notice that the
results page doesn't show duplicates, but still shows all
the items in their respective crates.

Rollup merge of #122247 - notriddle:notriddle/search-unbox-limit, r=GuillaumeGomez 
rustdoc-search: depth limit `T<U>` -> `U` unboxing

Profiler output:
https://notriddle.com/rustdoc-html-demo-9/search-unbox-limit/ (the only significant change is that one of the `rust` tests went from 378416ms to 16ms).

This is a performance enhancement aimed at a problem I found while using type-driven search on the Rust compiler. It is caused by [`Interner`], a trait with 41 associated types, many of which recurse back to `Self` again.

This caused search.js to struggle. It eventually terminates, after about 10 minutes of turning my PC into a space header, but it's doing `41!` unifications and that's too slow.

7b926555b7 rustdoc-search: add search query syntax Fn(T) -> U 
This is implemented, in addition to the ML-style one,
because Rust does it. If we don't, we'll never hear the end of it.

This commit also refactors some duplicate parts of the parser
into a dedicated function.
