Configure unified artifact coordinate type.

[ascopes]

This replaces the use of DependableCoordinate and ArtifactCoordinate outside a couple of locations that depend on the artifact resolver API as implementation detail. This will allow for adjusting the internal implementation later much more easily going forwards.

The use of .setExtension on the artifact/dependency types used for parameters is now deprecated and should be replaced with .setType instead. This will be removed in v2.0.0.

While this is technically a breaking change in the code itself, the new parameter type remains fully compatible with the current parameter type, so this is not a major version bump. Users should not see any difference in the API signature when using Maven XML to configure it.
