Subject: Refactor FormBuilder arguments and default config

* Do not reopen AV::Base to define default form builder
  Inside the load hook we are already in AV::Base context.

* Do not pass the given block to the form builder
  The block is evaluated in fields_for context using capture, with the
  builder as argument. This means we do not need to give the block to the
  FormBuilder itself.
