feat(ci): POC Bitrise iOS runners for E2E benchmarking [INFRA-3527]

Adds temporary optional workflow to benchmark iOS E2E builds and tests
on Bitrise-provided GitHub Actions self-hosted runners.

Changes:
- New temp-bitrise-ios-e2e.yml: workflow_dispatch-only benchmarking workflow
- run-e2e-workflow.yml: use_bitrise_runner boolean input, conditional runner
  routing, Vagrant path fix (guarded by boolean + platform check)
- run-e2e-smoke-tests-ios.yml: threaded use_bitrise_runner through all 13 jobs

Security: workflow_dispatch only trigger, hardcoded runner group name,
configure-keystores: false, sanitized diagnostics.

Existing CI pipeline behavior unchanged — all defaults preserved.
