[release/2.6] MIOpen: Get current device from Torch rather than HIP in handle creation pytorch#154549 (#2216)

(This is a cherry-pick of
pytorch#154549)

Get current device from Torch rather than HIP in MIOpen handle creation.
The device may have already been set from torch side, otherwise device
is set to 0 for handle. Additional audits of cudnn vs miopen Handle.cpp
file.
