[rustdoc] Add a marker to tell users that there are hidden (deprecated) items in the search results
Someone on mastodon rightfully pointed out that having a visual indication that some search results were hidden would be a good idea if the "hide deprecated items" setting is enabled. In particular if no results are displayed.
It looks like this:

Add new "hide deprecated items" setting in rustdoc
This PR adds a new JS setting which allows the JS to hide deprecated items. This is especially useful for crates like `std` which accumulates deprecated items but never removes them.
Nicely enough, the "deprecation" information was already in the search index, meaning I didn't need to change anything there. Before this PR, it was only used to make the deprecated items rank lower. Well now it's also used to generate an extra CSS class, allowing the JS setting to work.
This is taking over https://github.com/rust-lang/rust/pull/149551.
This feature got approved by the rustdoc team in the [meeting of december](https://rust-lang.zulipchat.com/#narrow/channel/393423-t-rustdoc.2Fmeetings/topic/2025-12-08/near/562553156).
You can give it a try [here](https://rustdoc.crud.net/imperio/hide-deprecated-items/foo/index.html).

Fix trait method anchor disappearing before user can click on it
A good example of this bug is going to https://doc.rust-lang.org/nightly/nightly-rustc/rustc_hir_analysis/collect/struct.ItemCtxt.html#impl-HirTyLowerer%3C'tcx%3E-for-ItemCtxt%3C'tcx%3E, and then try to click on the `§` anchor of the `tcx` method.
The solution to this bug is to simply "glue" the anchor to the method, so when the mouse cursor moves to it, there is no gap between the two, preventing the anchor to disappear (hopefully this explanation doesn't make sense only to me ^^').
First commit fixes the bug by expanding the anchor size.
Second commit is a small clean-up of the GUI test.
Third commit actually adds the GUI regression test.

[rustdoc] If line number setting is disabled, do not make line numbers take space
While working on https://github.com/rust-lang/rust/pull/150395, I realized that when enabled then disabled the "show line numbers" setting, instead of looking like initially:
<img width="904" height="148" alt="Screenshot From 2025-12-26 16-51-44" src="https://github.com/user-attachments/assets/a24df2f2-61be-4db5-b60f-519b35425fd2" />
The "space" taken by line numbers was still there:
<img width="904" height="148" alt="Screenshot From 2025-12-26 16-51-41" src="https://github.com/user-attachments/assets/b44af75d-52a4-4401-98e4-602b16bf6b9b" />
This PR fixes it.
First commit cleans up the `utils.goml` file a bit, I think I'll do more cleanup because switching the settings without reloading the page should make GUI tests a bit faster.

add test against crashing with --html-after-content file
correctly add --html-after-content to env not args
formatting fix for rustdoc-call-locations-after-content/rmake.rs
Use local crate source file as default span in `render_call_locations`
- avoids unwrapping the first file added to the source map as a local file in
`href_from_span`
move test to tests/rustdoc-gui, rename to scrape_examples_ice
test link is correct
use rustdocflags, rename path in example, track lock file
factor out duplicate function calls
use compile-flags to make sure the after.html file is actually included in the rustdoc call
fix goml go-to path
increment assert-count in sidebar-source-code.goml
adjust crate-search width in search-result-display.goml
renamed Bar in scrape_examples_ice test
make crate name shorter ..
When this fails, you get output that looks like:
/home/user/rust/tests/rustdoc-gui/search-result-impl-disambiguation.goml search-result-impl-disambiguation... FAILED
[ERROR] `tests/rustdoc-gui/utils.goml` around line 49
from `tests/rustdoc-gui/search-result-impl-disambiguation.goml` line 25: JS errors occurred: Event: Event
Making the error message more informative requires patching browser-ui-test.
