Rework to use KUKSA.val databroker gRPC API

Rework to move from the WebSocket API with the older KUKSA.val
server to the gRPC "VAL" API of the databroker.

Changes include:
- All VISS WebSocket API code has been removed, and the signal
  providers replumbed to be driven by a new VssClient class with
  a hvac-specific child class to hold all the gRPC API
  handling.
- The generated code for the VAL API and its dependencies has
  been checked in under lib/generated, as there still does not
  seem to be a good way to generate it during the Flutter build.
- The configuration file is now expected to be "hvac.yaml" instead
  of "hvac_config.yaml".  The authorization token field name has
  been renamed to "authorization", and there are new "use-tls" and
  "ca-certificate" configuration fields.  TLS is disabled by default
  for now, and the default CA certificate is /etc/kuksa.val/CA.pem.
- Bumped minimum SDK version to 2.18 in pubspec.yaml to enable
  "super" keyword support.  This matches what the version was set
  to in flutter-homescreen.
- The Vehicle and VehicleSignals classes have been reworked into
  a VehicleAcStatus class + provider, and users have been updated
  to use the Riverpod provider select functionality to attempt to
  reduce naive over-updating.
- VSS paths have been rationalized to use the definitions in the
  VSSPath class so only one location will need to be updated on any
  signal name changes.
- Added .gitignore file from flutter-homescreen to keep things
  clean in the future.
