Support advanced package assembly in multi-flavour repository

[AyanSinhaMahapatra]

When there are package manifests from multiple package ecosystems and we perform a package assembly for the package manifest that we find first, a top level package is created out of it, and while assigning resources, we ignore any package manifest of different type from package assembly as they do not match the data-file patterns of this package handler.

Suggested fix: While doing Package assembly even if a package data is in the seen_resource_paths here: https://github.com/nexB/scancode-toolkit/blob/develop/src/packagedcode/plugin_package.py#L351 but it has a package data in it which has different type from the top-level package that made this resource seen, do not ignore this resource. To track this we have to make the seen_resource_paths a dictionary with {"path": "package_type"} instead of a plain list.

See example at https://github.com/nexB/scancode-toolkit/blob/support-cargo-workspaces/tests/packagedcode/data/cargo/cargo-with-workspace.expected.json#L1527 where the package from this resource is not assembled because of a package.json at the root.
