[QNN Nuget Pipeline] Build with ML ops and detect ORT version (#19024)

### Description
- Removes `--disable_ml_ops` build flag 
- Automatically detects ORT version from VERSION file via
`templates/set-version-number-variables-step.yml`. We will no longer
need to create a commit to update ORT versions.

### Motivation and Context
- A new unit test caused failures in the QNN Nuget pipeline because it
did not enable ml ops.
- Automate ORT version specification
