tests/qtest/cmsdk-apb-watchdog-test: Parameterize tests

Currently the CMSDK APB watchdog tests target an specialized version
of the device (luminaris using the lm3s811evb machine) that prevents
the development of tests for the more generic device documented in:

https://developer.arm.com/documentation/ddi0479/d/apb-components/apb-watchdog/programmers-model

This patch allows the execution of the watchdog tests in an MPS2
machine (when applicable) which uses the generic version of the CMSDK
APB watchdog.

Finally the rules for compiling the test have to change because it is
possible not to have CONFIG_STELLARIS (required for the lm3s811evb
machine) while still having CONFIG_CMSDK_APB_WATCHDOG and the test
will fail. Due to the addition of the MPS2 machine CONFIG_MPS2
becomes also a dependency for the test compilation.
