Re-enable optimized gelu test in CMake (#8667)

* Fix log_softmax along non-contiguous dim

Pull Request resolved: #8595

#8382 certainly didn't fix this problem (and added it on x86), but I don't think it was correct on ARM prior to that either.

Added a regression test.

* Re-enable optimized gelu test in CMake

Pull Request resolved: #8597

I missed this line disabling the test. (Splitting out re-enable of log_softmax because I think that one needs fixes.)
