[GFC] Parameterize distributeExtraSpace to handle flexible tracks
https://bugs.webkit.org/show_bug.cgi?id=324480
rdar://187718970
Reviewed by Sammy Gill.
This PR implements the space distribution ratio of
https://drafts.csswg.org/css-grid-1/#algo-spanning-flex-items.
This PR adds distributeSpaceAmongFlexibleTracks to perform the space
distribution.
Space is distributed according to the track's fraction of the flex sum if the
flex sum >= 1,
otherwise distributes some fraction of the available space by each track's flex
fraction
and the rest equally.
No behavior change: an item spanning a single flexible track receives all of
the space
under either distribution, and coverage does not yet admit items spanning more
than one
track.
