…elines (#6988)

* Workaround assembly downgrade in SemanticKernel packages

* Enable warning as error in pipelines

And make source-index step use similar build entrypoint.

* Consistently apply warnAsError in BuildAndTest.yml

* Keep warnAsError disabled for PR validation

This allows folks to get test results without being blocked by warnings.

Make sure the job testing for warnings runs on windows to ensure it builds a superset of targets.
