qemu_x86 seems to take an extra instruction after the sti instruction
(irq_unlock) happens before it posts the interrupts. This can issues
if the instruction after the sti ends up reading the state that is
suppose to be updated by the ISR handler.
We see this behavior when building with LLVM. To workaround this issue
we add an arch_nop() to provide an extra instruction to allow the
interrupts to post.
Opened zephyrproject-rtos/sdk-ng#629 to track qemu issue.

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.

Add test cases of regular interrupt for arch x86. This tests basic
functionailty of IRQ_CONNECT(), irq_enable(), irq_disable(),
irq_lock(), irq_unlock().
