tests: interrupt: refine the interrupt testcases

This PR include 2 changes to refine the testcases:
1. Now we using IPI to trigger interrupt in testing instead of INT
   instruction, this means we don't need to hardcode the vector
   number. That can avoid some problem.

Fixes: #40374

2. Refined the test cases. Tigger interrupt by INT instruction and
   IPI cannot be masked by irq_disabled(). Unless it's a external
   interrupt, such as a timer. Now remove those incorrect part of
   these testcases.
