[IMP] mrp: Add new components in workorders

Purpose: adding new component in a specific workorder via the form view.
This behavior is only available if the Bill of Material is in flexible
consumption. Adding new component was already made possible in
e1f518bb83 but the ability to add new
workorder lines conditionnaly in the workorder form view was missing.
