Bug 13074: Use Koha::Cache to cache the defaults values of a MARC record

Bug 13074: Use Koha::Cache to cache the defaults values of a MARC record

With the global %default_values_for_mod_from_marc variable, the changes
made to the marc_subfield_structure table and especially the links
between MARC and DB fields are not safe and might be outdated (if a
field is linked/unlinked)

Test plan:
Under Plack:
- Link the barcode field, edit a record and set a barcode.
- Remove the mapping for the barcode field and then update again the
  barcode of the record.
The items.barcode DB field must not have been updated.

Without this patch, the field should have been updated.
