Add VTS tests for EFF/RTR

Remote transmission request, and extended format id's require testing to
verify that the feature works correctly.

Also included is a fix which correctly sets the EFF and RTR flags of the
canfd_frame object based on the state of the CanMessage object.

A readability change is made to the types.hal which improves clarity of
the way filters are defined.

Bug: 146173498
Test: run the VTS tests in vts/functional - verify that they pass
