c517dfde12 LibWeb: Honor the flexbox spec's "automatic minimum size" everywhere 
`min-width: auto` and `min-height: auto` have special behavior on flex
items. We already handled it in many cases but there were two places
where it was incorrectly treated as 0. This fixes that.

bad6ad8861 LibWeb: Implement CaseInsensitiveBytesTraits::equals() 
Turns out HashTable::contains() doesn't solely use hash() for equality
checks, so the lack of a proper equals() implementation broke the check
in convert_header_names_to_a_sorted_lowercase_set() and caused duplicate
entries in header_names_set.

2726fc9c73 LibWeb: Move Fetch infra into the Web::Fetch::Infrastructure namespace 
The Fetch spec unfortunately will cause a name clash between the Request
concept and the Request JS object - both cannot live in the Web::Fetch
namespace, and WrapperGenerator generally assumes `Web::<Name>` for
things living in the `<Name>/` subdirectory, so let's instead move infra
code into its own namespace - it already sits in a (sub-)subdirectory
anyway.

We have not yet implemented safely_extract_body so renaming this to
extract_body() and adding a spec link.

469491906f LibWeb: Add GradientPainting for painting linear-gradients 
This implements support for painting linear-gradients in a spec
correct way :^).

Right now it supports:

- Multi-stop gradients
- Color stop fixups
- Using pre-multiplied alpha mixing when required
- Painting gradients at arbitrary angles

It still needs to support:

- Transition hints
- Double position color stops

However what is implemented now seems to be accurate to other
browsers, and covers the most common use cases.

cbc04a6285 LibWeb: Support painting simple linear-gradients 
This is just a quick test that everything is working. Currently
it paints the gradients with the existing
painter.fill_rect_with_gradient(). This can only handle two-color
orthogonal gradients.

ae6c0258a4 LibWeb: Parse the linear-gradient() CSS function 
This should parse linear-gradient()s as defined in the W3 spec
https://drafts.csswg.org/css-images/#linear-gradients.

Note: This currently cannot parse multi-position color stops,
these are shown on MDN and work in Firefox and Chrome, though do
not seem to be defined in the spec.

See: https://developer.mozilla.org/en-US/docs/Web/CSS/gradient/linear-gradient#gradient_with_multi-position_color_stops

P.s. This also allows -webkit-linear-gradient for compatibility.

aa9f7cc597 LibWeb: Fix queuing mutation records for node removal 
Step 19 of node removal was missing, which allows the mutations of the
descendants of the removed node to still be observed by the parent.

Step 20 of node removal queued the mutation record for the removed
node instead of it's parent. Since queuing takes place after the node
is removed from the tree, the mutation record would be lost as the only
inclusive ancestor of the node at this point is only the node itself.

9b46091f38 LibWeb: Rename LayoutState::NodeState => LayoutState::UsedValues

884b7fad48 LibWeb: Remove weird is_undefined_or_auto() helper in FFC 
This was a leftover from when ComputedValues stored sizes in Optionals.
Now that we've gotten rid of the "undefined" state, there's no need for
this helper, we can just access the size values directly.
