This plugs a leak where resolve was treating enums defined in parent modules as in-scope for all children modules when resolving a pattern identifier. This eliminates the code path in resolve entirely. If this breaks any existing code, then it indicates that the variants need to be explicitly imported into the module. Closes #14221 [breaking-change]
