sink/codec(cdc): add message size check and support schema default

[zhangyangyu]

What problem does this PR solve?

Issue Number: ref #5338

What's changed and why?

1. there is a max-message-bytes limitation when using kafka sink, avro needs to respect it.
2. Avro protocol supports a default property for record, add support in TiCDC. For TiCDC, this doesn't matter for DML changes since TiCDC will getDefaultValueOrZeroValue for DML change, so we always have a value. But it's important for DDL(schema change). Optional and non-optional columns has different results when register schema into Confluent Schema Registry, https://docs.confluent.io/platform/current/schema-registry/avro.html#summary. Losing the default definition might fail the compatibility check.
3. goavro doesn't support set default value for logical type. So there is a known limitation that DECIMAL type will lose the default definition.

LGTM.
Do you have some e2e tests for the avro default value?

LGTM. Do you have some e2e tests for the avro default value?

Avro doesn't fit into the current IT framework now, which definitely should be improved in future. But I have done some manual e2e checks.
