reflect/protoreflect: improve source information usability

Added API:
  SourceLocations.ByPath
  SourceLocations.ByDescriptor
  SourceLocation.Next
  SourcePath.String
  SourcePath.Equal

We modify compiler/protogen to use SourceLocations.ByDescriptor.
In retrospect, if this had existed during the development of protogen,
we would not have exposed protogen.Location and related fields.
