drm/amdkfd: Refactor queue wptr_bo GART mapping

Browse Source 
Add helper function kfd_queue_acquire_buffers to get queue wptr_bo
reference from queue write_ptr if it is mapped to the KFD node with
expected size.

Add wptr_bo to structure queue_properties because structure queue is
allocated after queue buffers are validated, then we can remove wptr_bo
parameter from pqm_create_queue.

Rename structure queue wptr_bo_gart to hold wptr_bo reference for GART
mapping and umapping. Move MES wptr_bo_gart mapping to init_user_queue,
the same location with queue ctx_bo GART mapping.
