Clean up interface to PermissionPrompt and subclasses

Following https://crrev.com/c/567940, this patch greatly simplifies the
interface to PermissionPrompt as follows:
- Object creation and showing a prompt are now tied. Move Show() and
  SetDelegate() logic into the ctor.
- Hiding only happens by object destruction. Remove HidesAutomatically()
  and move Hide() logic ino the dtor.

This patch also cleans up MockPermissionPrompt{,Factory} accordingly,
moving some logic previously from MockPermissionPrompt::Show() to the
factory.
