Fixes #10247: Allow changing selected device/VM when creating a new component

Fixes: #10247

This work affects all device components, all device component templates, and VM interfaces. At a high level, we've switched from rendering two individual forms for component creation to a single new per-model creation form, which inherits from both ComponentCreateForm as well as the pertinent model form. This enables us to efficiently render the form and ditch a number of custom templates.

patterned_fields on the component creation views has been replaced with replication_fields, which is now defined on the form for more robust validation. Additionally, name_pattern and label_pattern have been renamed to name and label, and now replace the model form fields of the same names.

I still need to fix bulk component creation (e.g. for multiple objects).
