[grid][Masonry] Fix crash for standalone subgrid with auto-repeat

A subgrid axis on a grid/grid-lanes with no parent has a used value of
`none` (https://drafts.csswg.org/css-grid-2/#subgrid-listing). Its
trailing auto-fill line-name repeater can resolve to 0 repetitions,
which tripped DCHECK in `FinalizeRanges`.

Treat a standalone subgridded axis as contributing no explicit repeaters
so that we don't consider these repeaters in later stages, thus fixing
the crash for both grid and grid lanes.
