add install script validation to build pipeline (#541)

- Add initial validation for our install scripts
- Currently depending on log output for expected installed file
validation.
    - Checking installation directory existence.
    - Not checking actual install file dotnet dependency.
- Update pr/ci pipelines to run validation with build stage
