feat: copy packager_test.py in CMake (#1284)

This is used to run a fairly large number of integrations tests (which are exposing some failures on the CMake branch). Let's copy these over first to enable the integration tests workflow.

Actually running integration tests in CTest is off by default (gated by `SKIP_INTEGRATION_TESTS` while we fix the tests).
