Add fetchTags: false to all checkout steps in Azure Pipelines

[Copilot]

Description

Adds fetchTags: false to all 11 checkout: steps across 9 Azure Pipelines YAML files in eng/pipelines/. This prevents unnecessary Git tag fetching during repository checkout, optimizing CI pipeline initialization time.

Customer Impact

None. Internal CI optimization only.

Regression

No. This is a performance optimization, not a bug fix.

Testing

YAML syntax validated. No functional changes to build or test processes.

Risk

Low. The fetchTags: false parameter only affects what Git metadata is fetched during checkout. Build and test logic remain unchanged. Tags are not required for any existing pipeline functionality.

Original prompt

Update the checkout step in the runtime CI yml to specify fetchTags: false

Before/After on checkout steps looks pretty nice

Note: We're backporting this to 10.0/9.0 in aspnetcore. I assume you'll want to backport this too.
