Subject: Rework Riverpod provider usage

Replace the single Riverpod provider for all vehicle signals with
separate ones for each required signal used directly in the widgets
that require them.  This is more in line with recommended Riverpod
practice, and should avoids driving full widget tree rebuilds on
every signal received.

Bug-AGL: SPEC-4660
