drm/ttm/tests: Add eviction testing

Browse Source 
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.
