  Add MarkableTraits to FloatRect / FloatPoint / FloatSize

Reviewed by Chris Dumez.

This patch adds MarkableTraits to FloatRect / FloatPoint / FloatSize.
So that we can use Markable<FloatRect, FloatRect::MarkableTraits> easily.
We also add `fabsConstExpr` to ensure that this is becoming `constexpr`.
And use `isNaNConstExpr` too. Unfortunately they are not constexpr until C++23.
