[CSS Exclusions] shape-inside layout fails to adjust first line correctly for writing-mode: vertical-rl

Source/WebCore:

ExclusionShapes no longer maintain a private "internal" coordinate system,
they're now defined in logical coordinates. The createExclusionShape() method
now handles the one-time conversion from physical to logical coordinates.

Test: fast/exclusions/shape-inside/shape-inside-rounded-rectangle-fit-003.html

* rendering/ExclusionPolygon.cpp:
(WebCore::ExclusionPolygon::getExcludedIntervals): Removed logical to internal coordinate conversions.
(WebCore::ExclusionPolygon::getIncludedIntervals): Ditto.
(WebCore::ExclusionPolygon::firstIncludedIntervalLogicalTop): Ditto.
* rendering/ExclusionPolygon.h:
* rendering/ExclusionRectangle.cpp:
(WebCore::ExclusionRectangle::getExcludedIntervals): Removed logical to internal coordinate conversions.
(WebCore::ExclusionRectangle::getIncludedIntervals): Ditto.
(WebCore::ExclusionRectangle::firstIncludedIntervalLogicalTop): Ditto.
* rendering/ExclusionRectangle.h:
* rendering/ExclusionShape.cpp:
(WebCore::physicalRectToLogical): Convert a FloatRect defined with coordinates to logical coordinates.
(WebCore::physicalPointToLogical): Similar.
(WebCore::physicalSizeToLogical): Simlar.
(WebCore::ExclusionShape::createExclusionShape): Convert shapes from physical to logical coordinates.
* rendering/ExclusionShape.h:
(ExclusionShape): Removed internal to logical coordinate conversion utility methods.

LayoutTests:

For the vertical writing modes, verify that rounded rectangle shape-inside content is
adjusted in the logical down direction when it will not fit betwen the rounded corners.
