Allow EditEngine create and edit forms to be reordered
Summary:
Ref T9132. Ref T9908. Puts reordering UI in place:
- For create forms, this just lets you pick a UI display order other than alphabetical. Seems nice to have.
- For edit forms, this lets you create a hierarchy of advanced-to-basic forms and give them different visibility policies, if you want.
Test Plan:
{F1017842}
- Verified that "Edit Thing" now takes me to the highest-ranked edit form.
- Verified that create menu and quick create menu reflect application order.
