According to https://github.com/servo/servo/pull/3069 the cached thread local context is introduced for green threads. Now green threads has gone, and the existence of cache force us to create a `LayoutContext`, an `AssignISizes` and an `AssignBSizes` for each flow during parallel layout, so the pull request tries to remove it. And it also switch `assign_inline_sizes()` to accept a `LayoutContext` parameter, as according to my current design we need to do full layout to some flex items for column flexbox during assign isize traversal.
Part of #14123.

Collect scroll roots during the collect_stacking_context phase instead
of during display list construction. This will be useful in order to
collect containing block scroll roots as well as to give scroll roots
sequential ids in the future. This change also pulls stacking context
children out of the StackingContext struct itself, which should reduce
very slightly the memory used by the finished display list. This also
simplifies the DisplayListBuilder because it no longer has to maintain
a stack of ScrollRootIds and StackingContextIds and can instead just
rely on the program stack.

Simplify the way that stacking contexts are collected. Instead of
passing the StackingContextId down the tree, pass the parent
StackingContext itself. This will allow future patches to get more
information about the parent stacking context (such as location).
Also remove the return value of collect_stacking_contexts, which was
unused.

Background:
The changes to Servo code to support Stylo began in the `selectors` crate with making pseudo-elements generic, defined be the user, so that different users (such as Servo and Gecko/Stylo) could have a different set of pseudo-elements supported and parsed. Adding a trait makes sense there since `selectors` is in its own repository and has others users (or at least [one](https://github.com/SimonSapin/kuchiki)).
Then we kind of kept going with the same pattern and added a bunch of traits in the `style` crate to make everything generic, allowing Servo and Gecko/Stylo to do things differently. But we’ve also added a `gecko` Cargo feature to do conditional compilation, at first to enable or disable some CSS properties and values in the Mako templates. Since we’re doing conditional compilation anyway, it’s often easier and simpler to do it more (with `#[cfg(feature = "gecko")]` and `#[cfg(feature = "servo")]`) that to keep adding traits and making everything generic. When a type is generic, any method that we want to call on it needs to be part of some trait.
----
The first several commits move some code around, mostly from `geckolib` to `style` (with `#[cfg(feature = "gecko")]`) but otherwise don’t change much.
The following commits remove some traits and many type parameters through the `style` crate, replacing them with pairs of conditionally-compiled API-compatible items (types, methods, …).
Simplifying code is nice to make it more maintainable, but this is motivated by another change described in https://github.com/servo/servo/pull/12391#issuecomment-232183942. (Porting Servo for that change proved difficult because some code in the `style` crate was becoming generic over `String` vs `Atom`, and this PR will help make that concrete. That change, in turn, is motivated by removing geckolib’s `[replace]` override for string-cache, in order to enable using a single Cargo "workspace" in this repository.)

This happens asynchronously, just as it does in non-WebRender mode.
This functionality is a prerequisite for doing proper display-list-based
hit testing in WebRender, since it moves the scroll offsets into Servo
(and, specifically, into the script thread, enabling iframe event
forwarding) instead of keeping them private to WebRender.
Requires servo/webrender_traits#55 and servo/webrender#277.
Partially addresses #11108.

Instead of producing a tree of stacking contexts, display list
generation now produces a flat list of display items and a tree of
stacking contexts. This will eventually allow display list construction
to produce and modify WebRender vertex buffers directly, removing the
overhead of display list conversion. This change also moves
layerization of the display list to the paint thread, since it isn't
currently useful for WebRender.
To accomplish this, display list generation now takes three passes of
the flow tree:
1. Calculation of absolute positions.
2. Collection of a tree of stacking contexts.
3. Creation of a list of display items.
After collection of display items, they are sorted based upon the index
of their parent stacking contexts and their position in CSS 2.1
Appendeix E stacking order.
This is a big change, but it actually simplifies display list generation.

Two related fixes for border-collapse:
* Fix border collapsing across table-row-group flows
This fixes the border-end calculation for table rows whose borders are collapsed with rows in different rowgroups. The border collapsing code now uses an iterator that yields all the rows as a flat sequence, regardless of how they are grouped in rowgroups. It gets rid of `TableRowGroupFlow::preliminary_collapsed_borders` which was never correct. (It was read but never written.)
This may fix#8120 but I'm not 100% certain. (I haven't managed to reproduce the intermittent failure locally, and my reduced test case still fails but in a different way.)
* Fix confusing `push_or_mutate` API
This fixes a bug when recalculating border collapsing for an existing table row. The bug was caused by using `push_or_mutate` which has no effect if there is already a value at the specified index.
The fix switches incorrect `push_or_mutate` calls to use `push_or_set` instead. It also renames `push_or_mutate` to `get_mut_or_push` which I think is a less-confusing name for this method.

Table columns should be layed out according to the 'direction' property of the
table flow, regardless of the 'direction' property of any table-row,
table-rowgroup, etc. flows.
This fixes a number of the `direction-applies-to-*` tests in the CSS2.1 test
suite.
This also simplifies `propagate_column_inline_sizes_to_child` by separating
the code used for table cells from the code for non-cell flows.

Fixes#5300, which it is a rebase of.
Known issues:
* Collapsed borders do not correctly affect the border-box of the table
itself.
* The content widths of all cells in a column and the content height of
all cells in a row is the same in this patch, but not in Gecko and
WebKit.
* Corners are not painted well. The spec does not say what to do here.
* Column spans are not handled well. The spec does not say what to do
here either.

This fixes a bug in finding the top left corner of an RTL block in physical coordinates. (The old code used the `start` point of the `position` rect, which is not always the top left.)
It also fixes the setting of `position.start.i` in certain mixed LTR/RTL cases.
There is still a bug related to `position.size` for RTL blocks with margins. See the FIXME comments for details.

Only simple alphabetic and numeric counter styles are supported. (This
is most of them though.)
Although this PR adds a sequential pass to layout, I verified that on
pages that contain a reasonable number of ordered lists (Reddit
`/r/rust`), the time spent in generated content resolution is dwarfed by
the time spent in the parallelizable parts of layout. So I don't expect
this to negatively affect our parallelism expect perhaps in pathological
cases.
Reconstructed from #5138 via raw diffing.
