`grid-template-rows: fit-content(100px)` had no effect when the grid container lacked an explicit height, because the fit-content growth limit clamping was gated behind `available_size.is_definite()`. Fix by normalizing fit-content tracks with unresolvable percentage arguments to max-content during track initialization, then applying the fit-content clamp unconditionally. Fixes https://github.com/LadybirdBrowser/ladybird/issues/7730
