add support for new dependencyResolutionManagement (#400)

* move repo declartions

- Move repository declartions in MavenConfiguration.java to LoomRepositoryPlugin.java

* move repo declartions

- Move repository declartions in MinecraftMappedProvider.java to LoomRepositoryPlugin.java

* move repo declartions

- Move repository declarations in MinecraftProcessedProvider.java to LoomRepositoryPlugin.java

* do not add repositories if dependencyResolutionManagement is used

* Simplify the change on LoomGradlePlugin

- this is the suggestion from liach

* change name to follow fabric naming convension

- change getProjectUUID to getProjectUuid
- change PROJECT_MAPPED_CLASSIFIER to projectMappedClassifier

* remove MavenConfiguration.java

- the file currently do nothing.

* clean-up for all `instanceof` clause

* add DependencyResolutionManagementTest

* code cleanup

* Update src/test/resources/projects/dependencyResolutionManagement/projmap/src/main/resources/modid.accesswidener

* change project uuid to project full name
