Allow multiple package-configurations with same ID and provenance

[MarcelBochtler]

At the moment ORT does not allow package-configurations with the same ID and provenance, and throws an exception:

https://github.com/oss-review-toolkit/ort/blob/4e2f276fa5a459d05f30a69d34e6c38ae3f3135b/model/src/main/kotlin/utils/SimplePackageConfigurationProvider.kt#L74-L79

As package-configurations can be set up in multiple locations (.ort.yml and the directory given to --package-configurations-dir), it should be allowed to have multiple package-configurations with the same matchers.

For curations, this already works as expected, and the logic is to use the one from .ort.yml first, and the one configured for ORT afterward.

Very much related to https://github.com/oss-review-toolkit/ort/issues/6873.

As discussed @MarcelBochtler, please verify whether your use-case still makes use of SimplePackageConfigurationProvider and its check:

https://github.com/oss-review-toolkit/ort/blob/811daef3d35abb440a1ad044bcbf14738fc95767/plugins/package-configuration-providers/api/src/main/kotlin/SimplePackageConfigurationProvider.kt#L47-L58

I can confirm that the issue is still there. With the OrtConfig package configuration provider enabled in addition to our own one (implemented in a plugin) I get:
