  [LFC][IFC][shape-outside] Sample the shape to find the first position where content fits

Reviewed by Alan Baradlay.

If line content doesn't fit at all we should sample the shape until we find the next line position where it does.
Currently we just move directly to the float bottom.

* Source/WebCore/layout/floats/FloatingContext.cpp:
(WebCore::Layout::FloatingContext::constraints const):

In the shape case provide a bottom 1px down from the current position. We'll try again at that position if the content doesn't fit.
Also call lineOverlapsShapeMarginBounds() before getting the shape interval. This is needed for correctness in some edge cases.
