Skip tests by default in internal rolling builds

[Copilot]

Plan to skip tests in internal rolling builds

• Explore repository structure and understand current pipeline configuration
• Add a runTests parameter to azure-pipelines.yml (defaults to false)
• Update Windows job in azure-pipelines.yml to pass skipTests parameter based on runTests
• Update Ubuntu job in azure-pipelines.yml to pass skipTests parameter based on runTests
• Update correctness stage job (already has skipTests: true, verified it's correct)
• Validate the changes by reviewing the YAML syntax
• Run code review (passed with no issues)
• Run security checks (no security issues found)
• Address PR feedback: Add condition to codecoverage stage to only run when tests are executed
• Make codecoverage stage dependency conditional in post-build validation to prevent issues when stage is skipped

<issue_title>Don't run tests for internal rolling builds</issue_title>
<issue_description>We still are running tests in the azdo internal rolling builds.

This can create fragility in the official build and it also opens us up to a greater surface area in our production pipelines.</issue_description>

<agent_instructions>Please update azure-pipelines.yml so that it doesn't run tests. I think this should be specifying skipTests to the BuildAndTest.yml template. Adding a build parameter that would enable tests, but make it off by default.</agent_instructions>

Changes LGTM, but I defer to @joperezr on whether this will have any unintended negative effects

Pull request overview

This PR introduces a runTests parameter to Azure Pipelines that allows tests to be skipped by default in internal rolling builds, addressing fragility concerns and reducing production pipeline surface area. By defaulting runTests to false, tests are skipped in automatic CI builds while remaining available for manual execution when needed.

Key changes:

• Added runTests boolean parameter (default: false) for controlling test execution
• Updated Windows and Ubuntu build jobs to conditionally skip tests based on the parameter
