Fix UUID support

[Fokko]

Rationale for this change

The UUID support is a gift that keeps on giving. The current support of PyIceberg is incomplete, and problematic. Mostly because:

• It is an extension-type in Arrow, which means it is not fully supported: Writing UUID using PyArrow does not set the UUID logical type on Parquet arrow#46469 Support for grouping in UUID columns arrow#46468
• It doesn't have native support in Spark, where it is converted into a string. This limits the current tests, which are mostly Spark-based.

I think we have to wait for some fixes in Arrow upstream until we can fully support this. In PyIceberg, we're converting the fixed[16] to a UUID, but Spark does seem to error because the logical type annotation in Parquet is missing:
