[jerryyin]

The first commit is cherry-picked from #34532, and has been approved in #31849 (authored by @whchung ). Without the first commit, r1.15 branch will not build for the latest ROCm release.

The second commit is cherry picked from #710. Fixed the RNN V2 kernels by enabled the auto-tuning loop in ROCm path. It should also fix the warning "No RNN Algorithm Found." cudnn_recurrent_test used to have 68 failures on value difference, now is all passing
