-----------
Make TransformState changes to support transform-style:preserve-3d and
perspective only apply to direct DOM children.

<rdar://problem/102632597>
Reviewed by Simon Fraser.
This changes TransformState to support applying the flattening both before and
after the specified transform is accounted for,
and reverses which happens if 3d transform interop is enabled.
This is because flattening under interop is a property of the child rather than
the parent. We flatten just that child if it isn't
accumulating its parent's transform, rather than flattening all children
because we're not preserve-3d).
The existing TransformState only supported flattening after, which I believe
was always incorrect if we were pushing transforms onto
the state from innermost to outermost. This happens for
getBoundingClientRect/ApplyTransformDirection, and is why
preserve-3d-not-applied-to-ancestors.html
failed (despite not being affected being interop changes). These changes make
that test work correctly.

New test with spacers around preserve-3d, and confirming that point mapping
works correctly.

Fixed due to supporting flattening on the right 'side' regardless of which
order transforms are pushed to the
TransformState (innermost to outermost, or outermost to innermost).
