extend tests/kernel/arm_irq_vector_table to other platforms

[zephyrbot]

Reported by Andrew Boie:

This test is currently specific to ARM, but really is applicable to all architectures that use an array-type vector table for interrupts: ARM, ARC, and Xtensa. The test proves that it's possible for the end user to override the vector table with their own creation.

Extend this test to those architectures as well. The only arch-specific code is to trigger the interrupt from software. Rename the test so it is not ARM-specific.
