lib/tests: Add randstruct KUnit test Perform basic validation about layout randomization and initialization tracking when using CONFIG_RANDSTRUCT=y.

lib/tests: randstruct: Add deep function pointer layout test The recent fix in commit c2ea09b193d2 ("randstruct: gcc-plugin: Remove bogus void member") has fixed another issue: it was not always detecting composite structures made only of function pointers and structures of function pointers. Add a test for this case, and break out the layout tests since this issue is actually a problem for Clang as well[1].
