chore: run all integration tests in CI (#323)

- Migrated the CI workflow generation code from
`rules_swift_package_manager`.
- Updated all packages with integration tests to follow a naming
convention: `all_integration_tests`, `smoke_integration_tests`,
`all_test_params`.
- Update the root `BUILD.bazel` to list the packages with integration
tests and generate the appropriate `test_suite` and `ci_workflow`
declarations.
- Generate the CI workflow.
- Update CI workflow to be cancelable.

Closes #320.
