Allow record override from location everywhere

[djhi]

Problem

There's no way to redirect to an Edit form with modifications. This makes it cumbersome to prefill an EditForm (see e.g. ra-history Revert button).

Solution

We already have a mechanism to prefill a form from the location state or search query in useCreateController that we leverage for cloning.

• Extract this mechanism into a hook
• Refactor it to merge the location data into a provided record
• Use the hook in useAugmentedForm
• Test edition with this mechanism
• Document the useRecordFromLocation hook
