Also don't log error messages from the GraphicsContext3D if webGLErrorsToConsoleEnabled is false

When running layout tests in content_shell, we end up logging more information.
Since webGLErrorsToConsoleEnabled is false during layout tests, this change makes
sure we match the baselines.

[CSS Grid Layout] Refactor GridCoordinate to hold GridSpans
https://bugs.webkit.org/show_bug.cgi?id=112211

Reviewed by Tony Chang.

In order to bring more spanning knowledge to RenderGrid without having
duplicated GridSpan resolution, it became needed to store them into
GridCoordinate. Note that this change is needed as we can only resolve
all the positions with enough context in one place: when we place the
item in the grid.

Refactoring, no change in behavior expected.

* rendering/RenderGrid.cpp:
(WebCore::RenderGrid::GridIterator::nextEmptyGridArea):
Updated to create 2 GridSpans. Also fixed a style violation (PassOwnPtr
as local member, not sure why it wasn't caught earlier).

(WebCore::RenderGrid::placeItemsOnGrid):
(WebCore::RenderGrid::placeSpecifiedMajorAxisItemsOnGrid):
(WebCore::RenderGrid::placeAutoMajorAxisItemOnGrid):
(WebCore::RenderGrid::gridAreaBreadthForChild):
(WebCore::RenderGrid::findChildLogicalPosition):
Updated the original function after GridCoordinate internal representation change.

(WebCore::RenderGrid::insertItemIntoGrid):
Ditto. Also added a new overloaded function that does resolution after auto-placement.

(WebCore::RenderGrid::resolveGridPositionsFromAutoPlacementPosition):
Removed the extra GridSpan computation, which was wrong.

* rendering/RenderGrid.h:
(WebCore::RenderGrid::GridCoordinate::GridCoordinate):
Updated GridCoordinate to hold 2 GridSpan. Also removed the 2 position
constructor (it would have been a hazard), replaced by a 2 GridSpan constructor.
