Fix AvroCoder serialisation by introduction of AvroGenericCoder specialisation
URL: https://github.com/apache/beam/pull/10218
Introduction of AvroCoderRegistrar and AvroCoderTranslator in #8342 broke
AvroCoder behaviour for avro specific records - they are now always decoded as
GenericRecord.
With this change the new entity is created - AvroGenericCoder with
corresponding *Registrar and *Translator to be used for GenericRecord
coding/decoding.

> While trying to upgrade our pipelines from Beam 2.11.0 to Beam 2.16.0 we
> found that our SpecificRecords used in PCollection were being decoded as
> GenericRecords.
> After some investigation we found the specific commit/issue that we think did
> brake it:
> [https://github.com/apache/beam/pull/8342/files]
> https://issues.apache.org/jira/browse/BEAM-7103
> After the mentioned change all AvroCoders are serialized as simple urn:
> "beam:coder:avro:v1" which means they are deserialized / rehydrated as
> AvroCoder<GenericRecord>.
