[Flexbox] Unify the two flex layout codepaths into a single
render-tree-driven formatting context
https://bugs.webkit.org/show_bug.cgi?id=319837
Reviewed by Antti Koivisto.
Flex layout had two implementations behind one preference: a render-tree
fallback in RenderFlexibleBox, and an LFC-based flex formatting context that
the integration layer reached by building a Layout::Box tree and running
Layout::FlexFormattingContext over it.
This unifies them onto a single, render-tree-driven algorithm while keeping
the flex formatting context design. LayoutIntegration::FlexLayout
no longer builds a Layout::Box tree or a BoxGeometry mirror; instead it
collects the flex container's renderers into logical FlexLayoutItems and runs
the render-tree flex algorithm directly over them. The render-side algorithm
becomes
WebCore::FlexFormattingContext and is the one and only flex layout
implementation.
With a single algorithm the coverage gate is gone: canUseForFlexLayout and
its FlexAvoidanceReason machinery are removed (LayoutIntegrationCoverage keeps
its line/grid coverage), the FlexFormattingContextIntegrationEnabled preference
is removed, and the now-unused LFC flex core is deleted (Layout::FlexLayout,
LogicalFlexItem, FlexFormattingConstraints, FlexRect).
The flex geometry/query helpers are consolidated into a single
FlexFormattingUtils in the formatting-context directory. The shared,
render-reachable helpers are static and called as
FlexFormattingUtils::foo(flexBox, ...) from both RenderFlexibleBox and the
formatting context; the handful of render-only helpers become file-local
statics in RenderFlexibleBox. The render-side FlexLayoutUtils is deleted.
Non-flex callers (RenderBlock/RenderBox/RenderBlockFlow/InspectorOverlay)
continue to go through thin RenderFlexibleBox proxies, so nothing outside
RenderFlexibleBox reaches into the formatting context.
No new tests: this is a refactor with no intended behavior change. The one
behavior-affecting surface is content that canUseForFlexLayout accepted before
(it now runs the render-tree algorithm instead of the LFC one); everything
canUseForFlexLayout rejected was already render-tree-driven and is unchanged,
so the existing flex tests exercise the change.
