Update script to run CIs for a branch. (#19797)

### Description
<!-- Describe your changes. -->
- Support multiple include/exclude values. 
- e.g. can now run with `-i MacOS -i iOS` to run CIs for both Apple
platforms.
- Default to current branch if run from directory in repo.
  - make lazier usage possible

### Motivation and Context
<!-- - Why is this change required? What problem does it solve?
- If it fixes an open issue, please link to the issue here. -->
Improve tools.
