Overhaul of migration strategy

Browse Source 
- New models simply point to the old database tables
- Perform schema and data migrations on the old models first (in the part app)
- Swap model references in correct order

Ref: https://github.com/inventree/InvenTree/pull/10699
These models have been migrated from the following (existing) models:
- part.PartParameterTemplate -> common.ParameterTemplate
- part.PartParameter -> common.Parameter
To preserve the existing data, we will use the existing database tables.
For this to work, the existing models (part.PartParameterTemplate and part.PartParameter)
must have already had schema and migrations applied:
