cmd/protoc-gen-go, internal/filetype: clean up EnumType construction

Drop the dependency from generated files on prototype.Enum: Generated
code should only depend on runtime/proto{iface,impl}.

Drop the Enums, Messages, and Extensions returns form
filetype.Builder.Build. Of these, only Enums was used by generated code.
Change the generated init function to pass the builder a slice of values
to fill in (as is done for messages and extensions).

Remove the filetype dependency on prototype in preparation for
eventually dropping the prototype package entirely.

Next Generation Go Protocol Buffers

WARNING: This repository is in active development. There are no guarantees about API stability. Breaking changes will occur until a stable release is made and announced.

This repository is for the development of the next major Go implementation of protocol buffers. This library makes breaking API changes relative to the existing Go protobuf library. Of particular note, this API aims to make protobuf reflection a first-class feature of the API and implements the protobuf ecosystem in terms of reflection.
