Rollup merge of #125779 - GuillaumeGomez:copy-code, r=rustdoc-team
[rustdoc] Add copy code feature

This PR adds a "copy code" to code blocks. Since this is a JS only feature, the HTML is generated with JS when the user hovers the code block to prevent generating DOM unless needed.

Two things to note:
 1. I voluntarily kept the current behaviour of the run button (only when hovering a code block with a mouse) so it doesn't do anything on mobile. I plan to send a follow-up where the buttons would "expandable" or something. Still need to think which approach would be the best.
 2. I used a picture and not text like the run button to remain consistent with the "copy path" button. I'd also prefer for the run button to use a picture (like what is used in mdbook) but again, that's something to be discussed later on.

The rendering looks like this:

It can be tested [here](https://guillaume-gomez.fr/rustdoc/bar/struct.Bar.html) (without the run button) and [here](https://guillaume-gomez.fr/rustdoc/foo/struct.Bar.html) (with the run button).

Fixes #86851.

The tests present here are used to test the generated HTML from rustdoc. The goal is to prevent unsound/unexpected GUI changes.

This is using the browser-ui-test framework to do so. It works as follows:

It wraps puppeteer to send commands to a web browser in order to navigate and test what's being currently displayed in the web page.

You can find more information and its documentation in its repository.

If you need to have more information on the tests run, you can use --test-args:

$ ./x.py test tests/rustdoc-gui --stage 1 --test-args --debug

If you don't want to run in headless mode (helpful to debug sometimes), you can use --no-headless:

$ ./x.py test tests/rustdoc-gui --stage 1 --test-args --no-headless

To see the supported options, use --help.

Important to be noted: if the chromium instance crashes when you run it, you might need to use --no-sandbox to make it work:

$ ./x.py test tests/rustdoc-gui --stage 1 --test-args --no-sandbox
