9e23503c9c LibWeb: Align with spec "stretch auto tracks" step in GFC
Now, we will evenly distribute the remaining free space across tracks
using the auto max-tracks sizing function, exactly as the specification
states. Many tests are affected, but they are not visually broken.

Fixes https://github.com/SerenityOS/serenity/issues/22798

de32b77ceb LibWeb: Use separate structure to represent fragments in paintable tree
This is a part of refactoring towards making the paintable tree
independent of the layout tree. Now, instead of transferring text
fragments from the layout tree to the paintable tree during the layout
commit phase, we allocate separate PaintableFragments that contain only
the information necessary for painting. Doing this also allows us to
get rid LineBoxes, as they are used only during layout.

e7de5cb4d2 LibWeb: Bring CSS line-height closer to other engines
This patch makes a few changes to the way we calculate line-height:

- `line-height: normal` is now resolved using metrics from the used
  font (specifically, round(A + D + lineGap)).

- `line-height: calc(...)` is now resolved at style compute time.

- `line-height` values are now absolutized at style compute time.

As a consequence of the above, we no longer need to walk the DOM
ancestor chain looking for line-heights during style computation.
Instead, values are inherited, resolved and absolutized locally.

This is not only much faster, but also makes our line-height metrics
match those of other engines like Gecko and Blink.

b66f65dc9e LibWeb: Define if identifier represent area or line during layout [GFC]
This fixes regression introduced in
c03e025a32 by assuming that it is
possible to determine whether identifier stands for line or area
during parsing.

e4dd4808c4 Tests/LibWeb: Split "grid/named-tracks.html" into smaller layout tests
The file grid/named-tracks.html contained multiple subtests. Splitting
them into individual files will make it simpler to identify where is
the issue.
