[Masonry] Reorganize subgrid WPT tests

Move grid-lanes subgrid tests into two new subdirectories based on the
display type of the subgrid element:

 - grid-subgridded-to-grid-lanes/: Tests where a `display: grid` element
   uses subgrid within a grid-lanes parent.
 - grid-lanes-subgridded-to-grid-lanes/: Tests where a `display:
   grid-lanes` element uses subgrid within a grid-lanes parent
   (track-sizing/).

Also:
 - Remove redundant naming from test files now that the folder conveys
   context (e.g. grid-subgridded-to-grid-lanes → grid-lanes-subgrid).
 - Close gaps in the row/ test numbering (001c was missing, 002e-h were
   missing).

This change has no functional effect, but organizes things better as
we will need to add a lot more tests, and separating things out will
make them easier to find in the future.
