Add tests for ttm_bo_validate that focus on BO eviction and swapout. Update device funcs definition with eviction-related callbacks. Add alternative funcs where evict_flags() routes eviction to a domain that can't allocate resources (dubbed "busy manager" in the tests). Extract the common path of ttm_device init into a function.
