Review Comment:
I changed FileIO::DeleteFiles to take const std::vector<std::string>& to
match Arrow FileSystem::DeleteFiles, and added an ArrowFileSystemFileIO
override that resolves Iceberg file locations and delegates to
arrow_fs_->DeleteFiles(paths). I also added a LocalFileIO test for the bulk
delete path.
