alchemist: Introduce MaybePackageDetails

This patch follows the same pattern as MaybeEBuildMetadata: introduces
an enum that allows interleaving success/failure cases of package
loading and differentiating them statically at the same time.

While this new enum allows us cleaning up a few logic, this patch
focuses on introducing it with minimal changes.

This is a pure refactoring and not supposed to change any behavior.
