  Make FloatRect etc. constexpr and adopt nanRect to make it usable for "not-filled" FloatRect purpose

Reviewed by Justin Michaud and Mark Lam.

Use constexpr in FloatRect and related classes, and add `nanRect` concept to make it usable for "not-filled" FloatRect.
This is useful in subsequent SVG optimization instead of using `std::optional<FloatRect>`.
