drm/xe: Fix kunit integration due to missing prototypes

In order to avoid  -Werror=missing-prototypes, add the prototypes
in a separate tests/<test-name>_test.h file that is included by both
the implementation (tests/xe_<testname>.c, injected in xe.ko) and the
kunit module (tests/xe_<testname>_test.c -> xe-<testname>-test.ko).

v2: Add header and don't add ifdef to files that are already not built
when not using kunit (Matt Auld)
