7182a537f3 LibWeb: Reduce inaccuracies when creating rotation matrices 
When converting rotate transform functions `sin` and `cos` can sometimes
be inaccurate. To avoid these inaccuracies we:
 - Mod the angle to minimise inaccuracies in the first place.
 - Discard tiny (smaller than epsilon) values returned by `sin` and
   `cos` as inaccuracies.

This is in line with  other browsers (e.g. Gecko and WebKit).

f03c432b52 AK: Use simdutf for searching strings for a single code unit 
In the following synthetic benchmark, the simdutf version is 4x faster:

    BENCHMARK_CASE(find)
    {
        auto string = u"😀Foo😀Bar"sv;

        for (size_t i = 0; i < 100'000'000; ++i)
            (void)string.find_code_unit_offset('a');
    }

dfe776b722 WebDriver: Stop using the ancient Core::EventReceiver parent/child API 
Before this change, clients were kept alive by making them children of
the TCPServer object. This ownership model is going away (and this was
the only remaining use of it!) so let's just put the clients in a hash
table instead.

cfdc4bad7c LibWeb: Update more navigation code to spec

7c8c05ee82 LibWeb/Layout: Support visibility:collapse on table-row elements 
When a table row (or its group) is set to collapse, the row takes up no
vertical space in the layout.

We have to account for this in multiple places, so I've cached whether a
row is collapsed in the TableGrid::Row.

5d4a4e44fe LibWeb/Painting: Paint border-style: double using two solid borders 
Call paint_border() recursively, once for the outer line, and once for
the inner one. This is done in a lambda so that we can reuse it for a
couple of other line styles.

Border-radius behaviour doesn't match other browsers, and goes a bit
haywire in some cases. I've left some FIXMEs for someone who
understands the maths here better than I do. 😅

The LineStyle handling is moved to the start of the function, to avoid
unnecessary work.

This regressed in cd15b1a2c9.

If a prefixed number is out-of-range of a u64, stroul would previously
fall back to ULONG_MAX. This patch restores that behavior.

CSS grid specification states that for grid items with a replaced
element and a percentage preferred size or maximum size, the percentage
should be resolved against 0 during content-based minimum size
calculation. This makes sense, as it prevents replaced items from
overshooting their grid track while intrinsic track sizes are
calculated, and allows later track size resolution steps to scale
replaced items to fit their grid track.
