build: remove legacy integration test runner (#35985)

* integration tests target definitions in integration/BUILD.bazel updated to use a single dict
* payload tracking for integration tests updated to work under Bazel
* legacy integration_test CI job removed
* integration/run_tests.sh script no longer used in CI so it has been updated for running integration tests locally in the legacy way
