ci: Remove executing from requirements-testing.txt (#6619)

Remove the package from `requirements-testing.txt` and add it only as a dependency of the test suites that rely on it.
Change `executing` import used for `ExecutingIntegration` to be more specific so `test_shadowed_modules_when_importing_integrations` passes.
This is part of environment cleanup before moving the remaining testing dependencies to a uv dependency group.
