6a4d80b9b6 LibWeb/CSS: Integrate ParsingContext into the Parser
This is not really a context, but more of a set of parameters for
creating a Parser. So, treat it as such: Rename it to ParsingParams,
and store its values and methods directly in the Parser instead of
keeping the ParsingContext around.

This has a nice side-effect of not including DOM/Document.h everywhere
that needs a Parser.

30ba7e334e LibWeb/CSS: Avoid creating a new Parser unnecessarily
This attr() code can instead just tokenize the input manually, and then
re-use the existing Parser.

4d0537ee80 LibWeb/CSS: Make CSS Parser non-copyable/movable
We never actually need to do this, and doing so was complicated because
of the token stream, so just disable it altogether.

6da7a6eab5 LibWeb/CSS: Un-template some CSS Parser methods
A few of these are only ever called with T=Token, so let's simplify them
a bit.

As a drive-by change: Also correct the "unnecessairy" typos and use
discard_a_token().

1413760047 LibWeb/CSS: Split up Parser.cpp
This file has been a pain to edit for a while, even with the previous
splits. So, I've divided it up into 3 parts:
- Parser.cpp has the "base" code. It's the algorithms and entry-points
  defined in the Syntax spec.
- ValueParsing.cpp contains code for parsing single values, such as a
  length, or a color, or a calculation.
- PropertyParsing.cpp contains code for parsing an entire property's
  value. A few of these sit in a grey area between being a property's
  value and a value in their own right, but the rule I've used is "is
  this useful outside of a single property and its shorthands?"

This only moves code, with as few modifications as possible to make that
work. I did add explicit instantiations for the template implementations
as part of this, which revealed a few that are actually only compatible
with a single type, so I'll clear those up in a subsequent commit.

ee649fc13b LibWeb+WebContent+WebDriver: Bring session start and close up to spec
Lots of editorial spec bugs here, but these changes largely affect how
the unhandledPromptBehavior capability is handled. We also now set an
additional capability for the default User Agent string.

2583996e18 LibWeb+WebContent+WebDriver: Allow specifying multiple prompt handlers
WebDriver script authors may now provide either:
* A user prompt handler configuration to be used for all prompt types.
* A set of per-prompt-type user prompt handlers.

This also paves the way for interaction with the beforeunload prompt,
though we do not yet support that feature in LibWeb.

070c4a2045 LibWeb: Implement text-align: match-parent
At computed-value time, this is converted to whatever the parent's
computed value is. So it behaves a little like `inherit`, except that
an inherited start/end value uses the parent's start/end, which might
be different from the child's.

4f855286d7 LibWeb: Clamp layout content sizes to a max value instead of crashing
We've historically asserted that no "saturated" size values end up as
final metrics for boxes in layout. This always had a chance of producing
false positives, since you can trivially create extremely large boxes
with CSS.

The reason we had those assertions was to catch bugs in our own engine
code where we'd incorrectly end up with non-finite values in layout
algorithms. At this point, we've found and fixed all known bugs of that
nature, and what remains are a bunch of false positives on pages that
create very large scrollable areas, iframes etc.

So, let's change it! We now clamp content width and height of boxes to
17895700 pixels, apparently the same cap as Firefox uses.

There's also the issue of calc() being able to produce non-finite
values. Note that we don't clamp the result of calc() directly, but
instead just clamp values when assigning them to content sizes.

Fixes #645.
Fixes #1236.
Fixes #1249.
Fixes #1908.
Fixes #3057.

4cb2063577 LibWeb/CSS: Stop returning Optional for enum properties
While keyword_to_foo() does return Optional<Foo>, in practice the
invalid keywords get rejected at parse-time, so we don't have to worry
about them here. This simplifies the user code quite a bit.

d3057a9c79 LibWeb: Preserve opening quotation in string token original source text
Used by chess.com, where it stores URLs to assets in CSS URL variables.
It then receives the value of them with getComputedStyle() and then
getPropertyValue(). With this, it trims off the url('') wrapper with a
simple slice(5, -2). Since we didn't preserve the opening quotation, it
would slice off the `h` in `https` instead of the quotation.

d94906fa1a LibWeb: Only apply style for continuation nodes once
This fixes the very, _very_ slow loading of https://yzy-sply.com. The
`apply_style()` method also calls into this method recursively, so we

f5ba22d3e8 LibWeb/DOM: Don't use recursion for subtree traversal in Node.h
This change is mainly motivated by the fact that iterating in a loop
makes profiles easier to read and understand where time was spent in
traversal callback. Additionally, using a loop reduces function call
overhead and ensures constant stack usage.

But because we always update the title element (either the SVG or HTML

0f17ad9ebc LibWeb: Use fast CSS selector matching in default matches() code path
Before this change, checking if fast selector matching could be used was
only enabled in style recalculation and hover invalidation. With this
change it's enabled for all callers of SelectorEngine::matches() by
default. This way APIs like `Element.matches()` and `querySelector()`
could take advantage of this optimization.

0c5b61b7e1 LibWeb: Fix infinite repaint loop when cached display list is used
Before this change, `m_needs_repaint` was reset in
`Document::record_display_list()` only when the cached display list was
absent. This meant that if the last triggered repaint used the cached
display list, we would keep repainting indefinitely until the display
list was invalidated (We schedule a task that checks if repainting is
required 60/s).

This change also moves `m_needs_repaint` from Document to
TraversableNavigable as we only ever need to repaint a document that
belongs to traversable.
