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.

Add test cases that check how the state of dma fences in BO's
reservation object influence the ttm_bo_validation() flow. Do similar
tests for resource manager's move fence.

Add mock resource manager to test ttm_bo_validate() with non-system
placements. Update KConfig entry to enable DRM Buddy allocator, used
by the mock manager. Update move function to do more than just assign
a resource.

Add tests for ttm_bo_init_reserved() and ttm_bo_validate() that use
sys manager. Define a simple move function in ttm_device_funcs. Expose
destroy callback of the buffer object to make testing of
ttm_bo_init_reserved() behaviour easier.
