[release/8.0-staging] Add fetchTags: false to checkout steps in pipeline YAML files

[Copilot]

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

Changes

• Updated 8 YAML files containing 10 total checkout steps in eng/pipelines/:
  • Pipeline templates: base-job.yml, xplat-job.yml, build-job.yml
  • Stress test pipelines: http.yml, ssl.yml (2 occurrences each)
  • Path evaluation and build jobs: evaluate-paths-job.yml, global-build-job.yml
  • Official build jobs: prepare-signed-artifacts.yml

Note: Changes to eng/common/ templates were excluded as those are shared infrastructure files managed separately.

Example

- checkout: self
  clean: true
  fetchDepth: $(checkoutFetchDepth)
  fetchTags: false  # Added to skip tag fetching

Original prompt

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