ffc81cbfad LibWeb: Use Selectors instead of a String for :not() selectors
Rather than parsing the selector every time we want to check it, we
now parse it once at the beginning.

A bonus effect of this is that we now support a selector list in
:not(), instead of just a single selector, though only when using
the new parser.

776b1f4548 LibWeb: Make CSS::Selector reference counted
The end goal is to make the PseudoClass::not_selector be a Selector
instead of a String that is repeatedly re-parsed. But since Selector
contains a Vector of ComplexSelectors, which each have a Vector of
SimpleSelectors, it's probably a good idea to not be passing them
around by value anyway. :^)

8cae79cc8d LibWeb: Add 'PseudoElement' as a CSS SimpleSelector::Type
Same reasoning again! This is the last one.

While I was at it, I added the two remaining CSS2.2 pseudo-elements,
::first-line and ::first-letter. All 4 are handled in the new CSS
parser, including with the compatibility single-colon syntax. I have
not added support to the old parser.

96b2356cbb LibWeb: Add 'Attribute' as a CSS SimpleSelector::Type
Previously, SimpleSelectors optionally had Attribute-selector data
as well as their main type. Now, they're either one or the other,
which better matches the spec, and makes parsing and matching more
straightforward.

004ae453d1 LibWeb: Add context to new CSS parser, and deprecate the old one
The new one is the same as the old one, just in the new Parser's
source files. This isn't the most elegant solution but it seemed
like the best option. And it's all temporary, after all.

7fefe34797 LibWeb: Add remaining CSS AttributeMatchTypes
This adds:
- ContainsString     [att*=val]
- StartsWithSegment  [att|=val]
- StartsWithString   [att^=val]
- EndsWithString     [att$=val]

Renamed AttributeMatchType::Contains to ::ContainsWord for clarity.

5eb65286b6 LibWeb: Support :active pseudo-class for hyperlinks, :focus possibly
Adds support for the :active pseudo-class for hyperlinks (<a> tags
only).

Also, since it was very similar to :focus and an element having a
focused state was already implemented, I went ahead and implemented
that pseudo-class too, although I cannot come up with a working
example to validate it.

ee3a73ddbb AK: Rename downcast<T> => verify_cast<T>
This makes it much clearer what this cast actually does: it will
VERIFY that the thing we're casting is a T (using is<T>()).

820224bb48 LibWeb: Match the :not pseudoclass
When a Selector features a :not() pseudoclass we now check whether the
current element matches with the given selector in the :not and act
accordingly.

b53dac6e88 LibWeb: Add support for more pseudoclasses
:disabled, :enabled and :checked are now parsed and matched. There
surely are more nuances to consider.

This is stolen from the old parser, but it seems to parse fine :^)

5d180d1f99 Everywhere: Rename ASSERT => VERIFY
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)

Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.

We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.
