Improve Autofill API (Beta)

Description

The current Forms Autofill API mechanism assumes that it does not need to know about which Forms/FormElements are being filled. It only knows about the remote-system-side.

DataElementBlockBase.GetAutofillValues()

Call _autofillService.Service.GetSuggestedValues(selectedDatasource, mappingKeys);

Then call

AutofillProvider.GetSuggestedValues(datasource, remoteFieldInfos))

The DataElementBlockBase knows about its OwnerForm, but does not provide that information to Autofill.

As a result of this story, more context is given to the Provider.

• which Form
• current Element
• its ElementInfo
• httpRequest
• RemoteField, Datasource (which is mapped; this already existed)

Note: Autofill API is still in internal beta mode. So, Episerver did not increase the version number as we normally would when introducing a breaking change.
