bpo-32089: Fix warnings filters in dev mode (#4482)
The developer mode (-X dev) now creates all default warnings filters to order filters in the correct order to always show ResourceWarning and make BytesWarning depend on the -b option. Write a functional test to make sure that ResourceWarning is logged twice at the same location in the developer mode. Add a new 'dev_mode' field to _PyCoreConfig.
