Upgrade to using `apache-avro` 0.22

[JosephLenton]

Is your feature request related to a problem or challenge?

15 days ago the latest version (0.22.0) of apache-avro was released. This has come with approximately 34 breaking changes. This issue is to track upgrading to using it.

This in turn has internal fixes needed to get UUID partitions fully working in #2916

Describe the solution you'd like

• iceberg-rs changes from using apache-avro version 0.21.0, to 0.22.0.
• All breaking changes fixed.
• No new bugs added.

(I can make a start on this as I need UUID partitions. I suspect there will be places in the code I'll need to reach out and ask what is the code trying to do, and asking what correct looks like.)

I'm just going to dump code changes I've found here to capture them.

1. RecordField::order is gone

Before: In 0.21.0 the Avro docs order does nothing and is ignored. See: https://docs.rs/apache-avro/0.21.0/apache_avro/schema/struct.RecordFieldBuilder.html#method.order

Now: the order field is just gone.

2. The first_row_id needs to be serialised as i64 not u64

We are serialising a u64, however Avro now expects an i64 for a long, and the spec says it should be signed as well. https://iceberg.apache.org/spec/#manifest-lists
