arch: Extract PCStateCommon from PCStateBase.
This class has a lot of common functionality which all PCState classes
use, but in order to make it a true base class which provides the
complete interface for PCState-s throughout gem5, all its methods would
need to become virtual. That doesn't have to be the case today because
we use the literal full ISA specific PC class directly, but we need to
move away from that.
This change leaves PCStateBase empty, since we don't know what will need
to be accessible in base classes through a common/virtual interface.
Also, move methods which do not depend on the InstWidth template
parameter out of SimplePCState and into PCStateCommon. This avoids
having duplicate methods with the same contents which don't depend on
InstWidth.
