LP#2131687 Holdings editor radio button UI syncs across fields

Bug: if multiple radio button fields are visible in the holdings
editor, changes to one updates the UI of the others (the model
is unaffected in the other fields, just their UI changes).

This adds [name] to the radio button inputs so they bind to the
expected input on RadioControlValueAccessor and group correctly.

As per the helpful comment #6 on LP#2131687, we also need to
keep the [attr.name] binding on these radio inputs because of
Angular bug: angular/angular#11757.
