[GFC] Introduce AxisConstraint for grid layout constraints
https://bugs.webkit.org/show_bug.cgi?id=307177
<rdar://169813212>
Reviewed by Sammy Gill.
Replace weak optional-based GridLayoutConstraints with a strong type that
makes illegal constraint states unrepresentable at compile time.
Also rename FreeSpaceScenario::Indefinite to MaxContent for clarity, as it
represents infinite available space where flex tracks size from max-content.
