Aliaksandr Kalenik bdf2dbff98 LibWeb: Move min-height handling for independent FCs to parent context
Previously, GridFormattingContext handled its own min-height constraints
internally, which caused infinite recursion when min-height was an
intrinsic sizing keyword (e.g., min-height: max-content).

This change moves the responsibility to the parent formatting context
(BFC). When any box establishing an independent formatting context has
auto height but non-auto min-height:
1. BFC measures content height using a throwaway LayoutState
2. If content height < min-height, BFC passes min-height as definite
   available height to the child formatting context
3. Child FC runs once with correct constraints, unaware of min-height

Fixes https://github.com/LadybirdBrowser/ladybird/issues/4261 which
is corresponding to stack overflow on https://claude.ai/
