Fix TextAutosizer not to scheduleRelayout() for LayoutGrid::layoutBlock()

This patch fixes TextAutosizer not to scheduleRelayout() when it's
called from LayoutGrid::layoutBlock().

SubtreeLayoutScope was added in the same way as
LayoutFlexibleBox::layoutBlock() does, which is passed to TextAutosizer
to prevent it to call scheduleRelayout().

Widening the scope, because it turns out that it's not only TextAutosizer that calls markContainerChainForLayout with scheduleRelayout=true during the layout. See crrev.com/1896803002#msg6 and crrev.com/1896803002#msg7.

Fix TextAutosizer not to scheduleRelayout() by MarkContainerChainInLayout

This patch fixes TextAutosizer not to scheduleRelayout() when its
relayoutBehavior is AlreadyInLayout.

r378639 solved the same issue only when markContainerChainForLayout()
has SubtreeLayoutScope, but TextAutosizer does not always have
SubtreeLayoutScope.

To solve this case, MarkContainerChainInLayout is added to mark
container chain without scheduleRelayout(), even when
SubtreeLayoutScope is missing.

Prevent markContainerChainForLayout to scheduleRelayout() if isInPerformLayout()

When we're in layout, markContainerChainForLayout() is marking a
descendant as needing layout with the intention of visiting it during
this layout. We shouldn't be scheduling it to be laid out later.

Also, schedduleRelayout() must not be called while iterating
FrameView::m_layoutSubtreeRootList.

Cleanup partial changes to prevent scheduleRelayout()

crrev.com/389691 prevents scheduleRelayout() during layout
automatically in markContainerChainForLayout(), making callers of
setNeedsLayout() to explicitly avoid scheduleRelayout() unnecessary.

This patch cleans up previous efforts to explicitly avoid it.
