score: Rename interrupt stack symbols

Rename

  * _Configuration_Interrupt_stack_area_begin in _ISR_Stack_area_begin,
  * _Configuration_Interrupt_stack_area_end in _ISR_Stack_area_end, and
  * _Configuration_Interrupt_stack_size in _ISR_Stack_size.

Move definitions to <rtems/score/isr.h>.  The new names are considerable
shorter and in the right namespace.

Update #3459.
