rtems: Add RTEMS_INTERRUPT_LOCK_NEEDS_OBJECT

Browse Source 
If the RTEMS_INTERRUPT_LOCK_NEEDS_OBJECT define has a non-zero value,
then the interrupt lock operations require an object of type
rtems_interrupt_lock, otherwise no lock object is required.

This indication can be used to avoid the space overhead for lock objects
when they are not needed.  In this case, the lock operations will not
use a lock objects parameter.

Update #4957 and #5038.
