fix(cfe-borrow): generate minimal Form.xml without ChildItems for borrowed forms

Configurator generates borrowed forms with only properties + AutoCommandBar +
empty Attributes — no ChildItems. ChildItems appear only when modifications are
added via form-edit. Copying full ChildItems caused XDTO errors on complex forms
due to unresolvable references (CommonPicture, StyleItem, xr: namespace elements).

Changes:
- Remove ChildItems extraction and output from Borrow-Form
- Strip ChildItems from AutoCommandBar (keep only Autofill property)
- Both main and BaseForm sections now contain only properties + minimal AutoCommandBar
