[GFC] TrackSizingAlgorithm needs to know if the max track sizing function is
auto

Reviewed by Alan Baradlay.
Currently TrackSizingAlgorithm is unable to know if the max track sizing
function is auto. This causes us to skip over the "stretch auto tracks,"
portion of the algorithm because we fail to see these tracks. This
happens because in GridLayout::trackSizingFunctions we transform the
auto and fit-content max track sizing functions to max-content since the
spec says "in all cases, treat auto and fit-content() as max-content,
except where specified otherwise for fit-content()."
https://drafts.csswg.org/css-grid-1/#algo-terms
For now let's stop doing this transformation, watch out for auto and
fit-content in TrackSizingAlgorithm, and either match the max-content
behavior or other behavior as called out by the spec.
* Source/WebCore/layout/formattingContexts/grid/TrackSizingAlgorithm.cpp:
(WebCore::Layout::sizeTracksToFitNonSpanningItems):
I removed the fit-content stub logic here since we'll probably just
detect this in another case for the switchOn (or some other way if we
decide to try a different approach again).
