Instead of manually adding (aLineLeft, aBlockStart) when creating a shape,
add Translate() to let the shapes implement their only way to move their
origin. FloatInfo could then move the shapes after they're created.

circle() allows the user to define an empty flow area, so IsEmpty() needs to
be overridden.
The flow area defined by a shape needs to be clipped to the margin-box per
https://drafts.csswg.org/css-shapes/#relation-to-box-model-and-float-behavior
In the reftests, both clip-path and shape-outside uses the same value so
that it's easier to debug visually.
Add LogicalPoint::LineRelative() because we need to convert a point's I() to
the line-axis in nsFloatManager. LineRelative() differs from I() in all
'rtl' direction per

Create ShapeInfo as a base class for implementing all the shapes. In this
design, we only need to create the correct subclass in FloatInfo's
constructor whenever shape-outside is used rather than manually branching on
StyleShapeSourceType and StyleBasicShape in all the methods like
LineRight(), LineLeft(), etc.
The concrete subclass of ShapeInfo could focus on implementing how its shape
influence the flow area by overriding the needed methods in ShapeInfo.
Move ComputeEllipseLineInterceptDiff() and XInterceptAtY() under the scope
of ShapeInfo so that they could be used by BoxShapeInfo and all the other
ShpapeInfo subclasses yet to come.

Use move constructor for two reasons. 1) The copy constructor is needed only
when appending FloatInfo to mFloats, so using move constructor will likely
be more efficient if some of the member variables support move constructor.
2) Part 6 will added a UniquePtr member to FloatInfo, so using move
constructor becomes necessary.
Also change the return value of AddFloat() to void to simplify the code,
since all the other callers do not check the return value, and
BlockReflowInput::FloatAndPlaceFloat() only asserts in debug mode. I assume
it's safe to omit the OOM check.

Since the line direction affects the interpretation of float right or left,
we should check aWM has the same line direction as mWritingMode. And this
also guarantees that float added by AddFloat() has the same line direction
as when querying the available space via GetFlowArea().

The tests cases are designed based on the integer solution to the ellipse
equation (x/a)^2 + (y/b)^2 = 1, where x=36, y=32, a=60, b=40.

We need to consider the case when only one of the four corner radius is
specified. The two reftests are added to test 'border-top-right-radius' and
'border-bottom-right-radius', respectively.

In GetFlowArea(), "Shrink our band's height if needed." computation was
moved to the end because we need to pass the unmodified |blockEnd| to
compute LineRight() and LineLeft().
Revamp OutsetBorderRadii() to allow negative margin to reduce the radius,
but not below zero. Also implement the cubic formula required by the spec.
https://drafts.csswg.org/css-shapes/#valdef-shape-box-margin-box
OutsetBorderRadii() is now tailored only for margin-box with border-radius,
so it might no longer be suitable for other scenarios.

Per spec, float positioning and stacking is not affected by defining a float
area with a shape.
https://drafts.csswg.org/css-shapes/#relation-to-box-model-and-float-behavior
So all the call sites of GetFloatAvailableSpace() related to adding a
float are replaced by GetFloatAvailableSpaceForPlacingFloat().
<shape-box> with border-radius will be implemented in next part.

Also exchange the order of the second argument |aBSize| and the third
argument |aBandInfo| for GetFlowArea() so that aBCoord and aBSize are
grouped together. And it'll be prettier to add ShapeInfo behind BandInfo
in later part.

The operator new is infallable. Also change the return value to void
accordingly. The only caller doesn't even check the return value.

After using enum class, a switch-case warning in CombineBreakType is caught.
This is one of such kind safty checks that we would like to gain.
Fix it by adding default case for switch-case in CombineBreakType.

The new name makes the sense of the condition much clearer. E.g. compare:
NS_WARN_IF_FALSE(!rv.Failed());
with:
NS_WARNING_ASSERTION(!rv.Failed());
The new name also makes it clearer that it only has effect in debug builds,
because that's standard for assertions.
By changing signature of those two functions, we make compiler complain about
all their existing uses, so we can find all of them and convert them.
Some of the callsites of Get() with those properties are also converted, but not
all of them. It is fine because if there is any incorrect conversion, compilers
is able to find out now. So they are completely typesafe.
