[IMP] website_crm_partner_assign: improve 'Partner Assignment' and creation

- This commit removes `selection` widget given on 'Partner Level'
  and 'Activation' fields on contact form view to allow users to
  create records for them on the fly (with 'no_open' option).

- This commit moves geo-location related fields below the parter assignment
  related fields in the 'Partner Assignment' page of contact form view.

- This commit adds default lowest 'Partner Level' and 'Activation' (based on
  sequence) while creating assigned partner on the fly from opportunity form
  view. The purpose is to allow user to select the created partner again in
  'Assigned Partner' m2o, which displays only partners having 'Partner Level'
  (grade_id) set.
