Add new script dependency resolvers

Changes in new API for dependency resolvers (GenericDependenciesResolver) comparing to an old one (GenericResolver:
- Add ability to fast check whether artifact or repository is suitable for current resolver to distinguish between unsuitable resolvers and resolution failures
- Return all artifact resolution failures in ResultWithDiagnostics
- Use single string for artifact coordinates
- Add compound resolver that combines several resolvers
- Merge Direct and FlatLib resolver into single FileSystemDependencyResolver
- Mark resolve() method as suspend to indicate long operation
- Add credentials support for maven resolver (https://youtrack.jetbrains.com/issue/KT-27701)
