Score ISR - Minimize Capabilities When Not Simple Vectored
In particular CPU_INTERRUPT_NUMBER_OF_VECTORS and
CPU_INTERRUPT_MAXIMUM_VECTOR_NUMBER are only used on
Simple Vectored Architectures, so do not depend on
them being defined. This disables as much as possible
that is specific to the Simple Vectored Model and
not expected to be used on architectures which use
the Programmable Interrupt Controller model for
interrupt handler vectoring.
