[gobject-introspection] scanner: Remove typedef namespace cache

[Simon Feltman <sfeltman src gnome org>]

commit e9e74c102b7e7181d35f5db1c2927dae07ccdb20

    scanner: Remove typedef namespace cache
    
    Remove the caching of typedefs in Transformer._typedef_ns. This is no longer
    used due to the added _tag_ns cache which store tags rather than typedefs.
    Remove adding of callback typdefs to the typedef_ns since these were not
    being used anyhow.
