[AVRO-1385] Enum reader/writer resolution doesn't report errors

• Type: Bug

Description

According to the specification, when a reader enum does not contain all symbols from the writer enum, an error should be signaled.

ResolvingGrammarGenerator fails to report such errors.
In particular, mkEnumAdjust() silently maps unknown symbols of the writers with symbols named "No match for [writer symbol]".

Shouldn't this instead create an ErrorAction?
