Revert "Generalize at::manual_seed for all accelerators (pytorch#144370)"

This reverts commit eeb5739.

Reverted pytorch#144370 on behalf of https://github.com/clee2000 due to broke internal tests D68023262, probably the same problem as noted in the issue this PR is mentioned above ([comment](pytorch#144368 (comment)))
