Subject: [PATCH] Add support for softmaxcrossentropy loss to MIGraphX EP (#64)
 (#22603)

Add support for softmaxcrossentropy loss. This is already enabled on our
ROCm Fork of the MIGraphX EP


### Motivation and Context
Adds support for the SoftmaxCrossEntropyLoss operator and removes the
filtering of inputs here.
