internal/runtime/maps: small maps point directly to a group
If the map contains 8 or fewer entries, it is wasteful to have a
directory that points to a table that points to a group.
Add a special case that replaces the directory with a direct pointer to
a group.
We could theoretically do similar for single table maps (no directory,
just point directly to a table), but that is left for later.
For #54766.
