It adds an option (enabled by default) which collapses all implementors impl blocks.

Track devirtualized filenames
Split payload of FileName::Real to track both real and virtualized paths.
(Such splits arise from metadata refs into libstd; the virtualized paths look like `/rustc/1.45.0/src/libstd/io/cursor.rs` rather than `/Users/felixklock/Dev/Mozilla/rust.git/src/libstd/io/cursor.rs`)
This way, we can emit the virtual name into things like the like the StableSourceFileId (as was done back before PR #70642) that ends up in incremental build artifacts, while still using the devirtualized file path when we want to access the file.
Fix#70924
Such splits arise from metadata refs into libstd.
This way, we can (in a follow on commit) continue to emit the virtual name into
things like the like the StableSourceFileId that ends up in incremetnal build
artifacts, while still using the devirtualized file path when we want to access
the file.
Note that this commit is intended to be a refactoring; the actual fix to the bug
in question is in a follow-on commit.
Doc alias improvements
After [this message](https://github.com/rust-lang/rust/issues/50146#issuecomment-496601755), I realized that the **doc alias**. So this PR does the followings:
* Align the alias discovery on items added into the search-index. It brings a few nice advantages:
* Instead of cloning the data between the two (in rustdoc source code), we now have the search-index one and aliases which reference to the first one. So we go from one big map containing a lot of duplicated data to just integers...
* In the front-end (main.js), I improved the code around aliases to allow them to go through the same transformation as other items when we show the search results.
* Improve the search tester in order to perform multiple requests into one file (I think it's better in this case than having a file for each case considering how many there are...)
* I also had to add the new function inside the tester (`handleAliases`)
Once this PR is merged, I intend to finally stabilize this feature.

use is_empty() instead of len comparison (clippy::len_zero)
use if let instead of while let loop that never loops (clippy::never_loop)
remove redundant returns (clippy::needless_return)
remove redundant closures (clippy::redundant_closure)
use if let instead of match and wildcard pattern (clippy::single_match)
don't repeat field names redundantly (clippy::redundant_field_names)
Extend search
I realized that when looking for "struct:String" in the rustdoc search for example, the "in arguments" and "returned" tabs were always empty. After some investigation, I realized it was because we only provided the name, and not the type, making it impossible to pass the "type filtering" check.
To resolve this, I added the type alongside the name. Note for the future: we could improve this by instead only registering the path id and use the path dictionary directly. The only problem with that solution (which I already tested) is that it becomes complicated for types in other crates. It'd force us to handle both case with an id and a case with `(name, type)`. I found the current PR big enough to not want to provide it directly. However, I think this is definitely worth it to make it work this way in the future.
About the two tests I added: they don't have much interest except checking that we actually have something returned in the search in the cases of a type filtering with and without literal search.
I also had to update a bit the test script to add the new locally global (haha) variable I created (`NO_TYPE_FILTER`). I added this variable to make the code easier to read than just "-1".

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.
