Thanks @tarang-jain for the PR. There are a few issues, but in general the changes related to the current device resource look good.

This PR enables the use of
rmm::mr::current_device_resourcefor device allocations when RAFT is enabled. The AllocRequest object caches the rmm Memory Resource used for the allocation to ensure that the same resource is used during deallocation. Managed allocations use a custom defaultrmm::mr::managed_memory_resourcebecause RMM currently does not have a way to retrieve a "guaranteed" managed memory resource from the current device resource.
