-----------
[GFC] Update affectedTracksMatchingMinSizeFunction to handle all phases
https://bugs.webkit.org/show_bug.cgi?id=321574
<rdar://184683817>
Reviewed by Sammy Gill.
affectedTracksMatchingMinSizeFunction has been renamed to affectedTracks
and updated to support space distributions across tracks' intrinsic
maximums and max-content maximums, steps 5 and 6 of:
https://www.w3.org/TR/css-grid-1/#track-size-max-content-min
This refactor also updates:
MinTrackSizingFunctionType -> GridItemSizeContributionType
and adds ForIntrinsicMaximums and ForMaxContentMaximums
to the renamed enum class.
We have also renamed
isMinTrackSizingFunctionValidForType -> shouldTrackAccommodateContributionType
isMaxTrackSizingFunctionValidForPhase ->
isTrackAffectedForSpaceDistributionInPhase
To better reflect the new track sizing steps we are supporting.
The affected track lists in steps 5 and 6 of:
https://www.w3.org/TR/css-grid-1/#track-size-max-content-min
Are created and temporarily marked as UNUSED_VARIABLE
