[release/9.0-staging] Add fetchTags: false to all checkout steps in CI pipelines

[Copilot]

Adds fetchTags: false to all Azure Pipelines checkout steps to skip fetching git tags during repository checkout, reducing CI checkout time and network overhead.

Changes

Updated 11 checkout steps across 9 pipeline files:

• Core build pipelines: global-build-job.yml, xplat-job.yml, run-test-job.yml
• Stress test pipelines: http.yml (2 checkouts), ssl.yml (2 checkouts)
• Utility pipelines: evaluate-paths-job.yml, deploy-to-onefuzz.yml, publish-build-assets.yml
• Performance pipelines: perf-job.yml (dotnet-performance repo checkout)

Example change

- checkout: self
  clean: true
  fetchDepth: $(checkoutFetchDepth)
  fetchTags: false  # Added

Original prompt

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