drm/ttm/tests: Add tests for ttm_resource and ttm_sys_man
Test initialization of ttm_resource using different memory domains.
Add tests for a system memory manager and functions that can be
tested without a fully-featured resource manager. Update
ttm_bo_kunit_init() to initialize BO's kref and a genuine GEM drm
object. Export ttm_resource_alloc for test purposes only.
