Fix 'minimal_power' to 'minimum_power' for DirectML performance selection (perf test) (#24303)

In Perf Test for DirectML EP, for the "performance_preference" runtime
key we could not select the "minimum_power" value option due to a small
bug. This PR fixes it so that "minimum_power" can be used and ran. I
will also link the respective issue to this PR

I made the change, built onnxruntime, and tested the perf_test.exe +
DLLs on a system with Intel Integrated Graphics + Nvidia dGPU. Switching
between 'minimum_power' and 'high_performance', I can see the options
respectively choose Intel Integrated and Nvidia dGPU as device runtimes
respectively (I checked task manager utilization for both devices). Both
inferences complete with no problems. I am attaching a reproducer here
with the built perf_test and the commands I tried to test it:
