style: Add a document state invalidator.
Don't use it yet (since I was working from a Servo tree). Will hook it up and improve in the Gecko bug.
Right now it takes a `StyleRuleCascadeData`, which means that if all the origins in the document have state selectors we could do just one walk over the tree and not multiple, that will be improved.
Other than that, this is completely untested of course, but I prefer to land it, given I don't think it's complex, and work on the Gecko integration separately. The reason for this is that I also plan to fix the `<slot>` bugs, which will change `StyleRuleCascadeData` and such, and I want the two bugs to conflict as little as possible.

Allow warnings during mutation tests.
Sometimes mutations include removing the only use of a variable. When we deny warnings globally, we inhibit these mutations that trigger new warnings.

Add note to Gentoo setup to set LIBCLANG_PATH envvar
<!-- Please describe your changes on the following line: -->
Without `LIBCLANG_PATH` environment variable set the build for `gecko-media` fails as in https://github.com/servo/servo/issues/19351 for Gentoo Linux. This patch adds a note to the README to set the environment variable.

style: Remove some unneeded indirection.
All TElement's implement Copy, and are just pointers, so the double indirection
is stupid.
I'm going to try to see if removing this double-indirection fixes some
selector-matching performance, and this is a trivial pre-requisite while I wait
for Talos results.

number input type validations
I used rust's builtin float parser to implement this. Rust's parser is more permissive than what browsers support (in this case), so I added some code to handle those edge cases.
This passes all the prewritten test cases locally, but I fell asleep last night before updating the manifests 😅
