lib/prime_numbers: convert self-test to KUnit

Extract a private header and convert the prime_numbers self-test to a
KUnit test. I considered parameterizing the test using
`KUNIT_CASE_PARAM` but didn't see how it was possible since the test
logic is entangled with the test parameter generation logic.

lib: math: Move KUnit tests into tests/ subdir

This patch is a follow-up task from a discussion stemming from point 3
in a recent patch introducing the int_pow kunit test [1] and
documentation regarding kunit test style and nomenclature [2].

Colocate all kunit test suites in lib/math/tests/ and
follow recommended naming convention for files <suite>_kunit.c
and kconfig entries CONFIG_<name>_KUNIT_TEST.

lib/math: Add int_pow test suite

Adds test suite for integer based power function which performs integer
exponentiation.

The test suite is designed to verify that the implementation of int_pow
correctly computes the power of a given base raised to a given exponent.

The tests check various scenarios and edge cases to ensure the accuracy
and reliability of the exponentiation function.
