Include ASG for all private and protected PVs

Set a default ASG for private PVs (ending in _, which should not be changed
outside the IOC) as private, and protected PVs (ones which would change the
behavior of EVR or EVG) as protected. For both cases a macro was included to
allow change which ASG name should be used
