fix: table UUID partitions not working

[JosephLenton]

Which issue does this PR close?

Table Partitions work on writing with UUID values.

• Closes Partitions with type UUID fail to create transactions #2913

What changes are included in this PR?

• PrimitiveLiteral::UInt128 will now convert to a RawLiteralEnum::String, when the type is UUID.
• A similar case is added to RawLiteralEnum for UUID deserialisation.

Are these changes tested?

I added:

• an integration test to confirm the UUID partition works.
• a second test to confirm writing all of the primitive types work.

A few notes ... Avro has an avro::Value::Uuid type so I did look into adding a RawLiteralEnum::Uuid type. Then the types internally could all match up. However this doesn't play well with Serde + apache_avro::to_value. Uuid will only serialise to bytes or a string.

The other thing I found is with the integration tests. I found when I had multiple tests in the same file it would fail with a Reqwest + Tokio error. I believe in opendal-core there is a global Reqwest client, and this will keep sessions alive across multiple tests within the same program (i.e. a single integration test). It doesn't do this if the endpoint changes (this is relevant later).

As a workaround I put my second test into a second file.

I'd be happy to try to solve this in a followup ticket if there is interest, and any other work to make test simpler. The solution is technically straight forward, but would be a chunk of code. We are talking a custom S3 storage layer, changing OpenDal core, or moving to use test-containers (as the endpoint will be different across tests). So I've left that out.

Thanks @JosephLenton for this fix!

We should not add more integration tests in this mod, it only exists for compatibility.

If you want to add such kind of test, you should add some slt test in datafusion integration.

I want to see ut for this change
