• Part of [EPIC] A collection of items to improve speed of parquet metadata encoding #5853.

Rationale for this change

Structures that are to be Thrift serialized as fields in another struct must implement the WriteThriftField trait. In most instances the implementation of that trait is trivial and adds unnecessary verbosity to the code.

What changes are included in this PR?

Add a new write_thrift_field macro that generates this boilerplate code.

Are these changes tested?

Covered by existing tests

Are there any user-facing changes?

No

@mbrobbel @alamb It's not critical this make it into 57.0.0. Should I mark this draft or set the milestone to 57.1.0 so it doesn't clog the review queue?
