LP#1857150: eg-fm-record-editor: add isDirty() method

This adds an isDirty() method to the form that components embedding
an eg-fm-record-editor can use to check whether the form is
currently dirty.

NOTE: not all of the custom components that can show up on
      an fm-edit form currently implement component-level
      dirty checks.
