Reformat files in the Iceberg connector

[ZacBlanco]

Description

Reformatting to match style guidelines

Motivation and Context

As a part of the project, we have a set of checkstyle guidelines. Generally we recommend developers to use IntelliJ for Java development. If you use the official style guidelines and format with the provided style rules within IntelliJ there are a number of files in the Iceberg connector which don't follow the official formatting rules. Maven checkstyle isn't capable of finding them all automatically.

The changes in this commit are the result of running IntelliJ's reformat procedure on all the files in the Iceberg connector using Presto's officially-provided style rules.
