[CSS Grid Layout] Adding or removing grid items doesn't properly recompute the track sizes
https://bugs.webkit.org/show_bug.cgi?id=109100

Test: fast/css-grid-layout/grid-item-removal-track-breadth-update.html

The test uncovered several bugs in our implementation that is fixed as part
of this change. They will be detailed below.

* rendering/RenderGrid.cpp:
(WebCore::RenderGrid::logicalContentHeightForChild):
Added this function to share the code between minContentForChild and maxContentForChild.
Also forced a relayout in this case to avoid getting a wrong answer (e.g. the logical height
constrained by the previous layout's grid breadth).

(WebCore::RenderGrid::minContentForChild):
(WebCore::RenderGrid::maxContentForChild):
Updated to use logicalContentHeightForChild.

(WebCore::RenderGrid::resolveContentBasedTrackSizingFunctions):
Updated to match the specification and set max breadth to current breadth per the specification.
This made us over-grow some cases in the test.

(WebCore::RenderGrid::distributeSpaceToTracks):
Updated to match the specification and use an extra variable to do the intermediate spreading. Also removed
a now unneeded max. This fixes the case of multiple grid items in the same grid area that was completely broken.

(WebCore::RenderGrid::layoutGridItems):
Added a FIXME about always relaying out content sized tracks' children.

* rendering/RenderGrid.h:
Added logicalContentHeightForChild.
