irq: Introduce and use CPU_INTERRUPT_SSTEP_MASK.

This mask contains all of the bits that should be ignored while single
stepping in the debugger.  The mask contains 2 bits that are not currently
cleared, but are also never set.  The bits are included in the mask for
consistency in handling of the CPU_INTERRUPT_TGT_EXT_N bits.
