There were two kinds of layout tracing controlled by the same debugging
option:
- modern layout: Functionality that dumped a JSON serialization of the
layout tree before and after layout.
- legacy layout: A scope based tracing that reported the process of
layout in a structured way.
I don't think anyone working on layout is using either of these two
features. For modern layout requiring data structure to implement
`serde` serialization is incredibly inconvenient and also generates a
lot of extra code.
We also have a more modern tracing functionality based on perfetto that
we have started to use for layout and IMO it's actually being used and
more robust.

- Remove the `LayoutBox::InlineBox` variant that was only used for
inline level boxes. Now they are stored in `LayoutBox::InlineLevel`
along with other kinds of out-of-flow and atomic inline items.
- Reduce the size of `InlineItem` by 260 bytes per item by using atomic
indirection / pointers. This adds a bit of overhead to access items in
exchange for a lot of memory saved.

This change fixes all rustdoc errors and also adds a tidy check for a
very common rustdoc URL issue. Eventually rustdoc warnings should likely
cause the build to fail, but this catches those issues sooner in order
to not waste so much developer time.

Refactor inline layout to allow rendering line items in the second stage
to be rendered in any order, independent of their parent inline box.
This will allow line items to be reordered, effectively allowing the
splitting of inline boxes, for the purposes of BiDi and any other inline
reordering feature.
