Create and activate product attributes lookup table in data migration

Until now the product attributes lookup table had to be created
and its usage had to be activated manually, via the tools page.
This commit does the following:

1. Remove the tools to create and delete the table
   (but keeps the tool to regenerate the table data for one or for
   all the products)

2. Creates a data migration that triggers the table creation and
   filling (unless the table already existed) for Woo 6.1

3. After the migration finishes, activates the table usage for
   product filtering (site admin can still disable it via
   Settings - Products - Advanced)
