Cleanup: Use DNA defaults for cloth modifier

Followup for rB8398050695
This requires moving a few enum definitions to DNA instead of BKE, and
adding default definitions for the two structs the cloth modifier where
the cloth modifier stores its settings. The defaults are also reordered
to be consistent with the order of each item in the struct.
