Fix item spacing of list replacement content in squoosh (#1686)

Fixes #1541. Set the default flex_grow value to 0 for list replacement
items. This prevents the items in the list from stretching to fit the
container they are in.

This change puts several of the validation tests previously in the
DEFAULT_RENDERER_ONLY category into the BOTH category. Squoosh is now
able to render these examples correctly, with some (CrossAxis Fill)
being more correct than the non-squoosh version.
