Subject: [PATCH] [chore](regression) Enable branch-4.2 pull request CI routing

### What problem does this PR solve?

Issue Number: close #xxx

Related PR: None

Problem Summary: Pull requests targeting branch-4.2 are not mapped to the community TeamCity pipelines, and Vault P0 rejects branch-4.2 during preparation. Add the same pipeline matrix used by branch-4.1, excluding Performance and ARM, and allow Vault P0 preparation for branch-4.2.

### Release note

None

### Check List (For Author)

- Test: Manual test

    - Validated shell syntax and the exact branch-4.2 pipeline mapping.

- Behavior changed: Yes (pull requests targeting branch-4.2 are routed to the supported community CI matrix)

- Does this need documentation: No
