layout: Simplify and generalize the usage of pseudo-elements (#36202)
- Remove the last remaining Servo-specific PseudoElement enum from
  layout. This was made to select `::before` and `::after` (both eager
  pseudo-elements), but now `traverse_pseudo_element` is called
  `traverse_eager_pseudo_element` and should work on any eager pseudo
  element.
- Expose a single way of getting psuedo-element variants of
  ThreadSafeLayoutElement in the Layout DOM, which returns `None` when
  the pseudo-element doesn't apply (not defined for eager
  pseudo-elements or when trying to get `<details>` related
  pseudo-elements on elements that they don't apply to).
- Ensure that NodeAndStyleInfo always refers to a node. This is done by
  making sure that anonymous boxes are all associated with their
  originating node.

These changes are prepatory work for implementation of the `::marker`
pseudo-element as well as ensuring that all anonymous boxes can be
cached into the box tree eventually.

layout: Take percentage columns into account when sizing table grid min and max (#35167)
The specification doesn't say how to deal with percentages when
determining the minimum and maximum size of a table grid, so follow the
approach that Chromium uses.

Essentially, figure out the "missing" percentage from the non-percentage
columns and then use that to work backwards to fine the size of the
percentage ones.

This change is larger than one might expect, because this percentage
approach shouldn't happen for tables that are descendants of a flex,
grid or table container (except when there is an interceding absolute).
We have to pass this information down when building the box tree. This
will also make it easier to improve propagated text decorations in the
future.

Elide lifetimes where possible after rustup (#34824)
The new version of rust allows us to elide some lifetimes and clippy is
now complaining about this. This change elides them where possible and
removes the clippy exceptions.

Fixes #34804.

layout: Add LayoutBoxBase and use it for IndependentFormattingContext (#34507)
Add a new struct `LayoutBoxBase`, that will be used throughout the box
tree. The idea of this struct is that we have a place to consistently
store common layout information (style and node information) and also to
cache layout results such as content sizes (inline and maybe later box
sizes) and eventually layout results.

In addition to the addition of this struct,
`IndependentFormattingContext` is flattened slightly so that it directly
holds the contents of both replaced and non-replaced elements.

This is only added to independent formatting contexts, but will later be
added to all block containers as well.
