Subject: [PATCH] cmake: Apply COMPILER_WARNINGS_AS_ERRORS also to nativesim
 runner

When COMPILER_WARNINGS_AS_ERRORS is set, let's also have the
native simulator runner (and anything Zephyr requests built with it)
be built with the same option to treat warnings as errors.
Otherwise we will miss those by default in CI.
