Revert "Support SqlTypes Date and Timestamp (MicrosInstant) in AvroUtils"

[Abacn]

Fixes #24415

Reverts #23969

#23969 introduced

• a one direction mapping from LogicalType(Date) to Avro Logical Type Data
• and a bidirectional mapping between LoficalType(SqlTypes.TIMESTAMP) Avro Logical type TimestampMicros

However, SqlTypes.TIMESTAMP (portable micros_instant) is not yet supported in Beam SQL (though its comments say Beam LogicalType corresponding to ZetaSQL TIMESTAMP type, which is not true yet)

This is a regression of Beam 2.44.0. Though It should be safe to make mapping of LoficalType(SqlTypes.TIMESTAMP) -> Avro Logical type TimestampMicros one directional as Date, however, defer this to future releases.

Kotlin example actually passed but not updated to GitHub UI: https://ci-beam.apache.org/job/beam_PreCommit_Kotlin_Examples_Commit/2800/

Will get this in and need a cherry pick to release-2.44.0 branch
