Add Support for Renaming Enums

[allenkaplan]

Is your feature request related to a problem? Please describe.
Rename/change enum names similar to renaming models https://prisma.typegraphql.com/docs/advanced/renaming-model/

Describe the solution you'd like
annotate similar to how models are done /// @@TypeGraphQL.type(name: "newName")

Describe alternatives you've considered
rebuild the enum with the desired name manually

Additional context
we have conflicts from legacy declared enums in our app and newer ones we want to use from prisma enum, but when trying to have them both we run into an error

Error: Schema must contain uniquely named types but contains multiple types named "FooEnumName".
