Enable CodeQL for Android build as per 1CS requirement. (#16875)

### Description
<!-- Describe your changes. -->
Split stages for CPU and CPU+NNAPI builds as CodeQL is enabled at the
stage level.
We run it for CPU+NNAPI as that covers all the Android code. 
We don't want to run it for both as duplicate issues would be created
for a problem in code included in both builds.

### Motivation and Context
<!-- - Why is this change required? What problem does it solve?
