[Feature Request]: Apply encryption when writing to Iceberg

[ahmedabu98]

What would you like to happen?

Currently we just write plain text files:

beam/sdks/java/io/iceberg/src/main/java/org/apache/beam/sdk/io/iceberg/RecordWriter.java

Lines 70 to 73 in dcf4839

	OutputFile outputFile;
	try (FileIO io = table.io()) {
	outputFile = io.newOutputFile(absoluteFilename);
	}

We should wrap these files in encryption before writing to them. Something like this

table.encryption().encrypt(outputFile)
