LibWeb: Flexbox: Take parents' specified main size into account

Browse source 
Previously, if the parent of the container had a definite main size, it
would've been disregarded when calculating the main size of the
container if it had no definite size and neither min- nor max-main-size
constraints.
This patch fixes that behavior by additionally checking whether the main
size is not only not constrained but also infinite.
