Description

In the serialized xml string of  RelXmlWriter, the 'Property' label is aligned.

For the sql below

select 1 + 2, 3 from (values (true))

the serialized xml string is like this:

<RelNode type="LogicalProject">
	<Property name="EXPR$0">
		+(1, 2)	</Property>
	<Property name="EXPR$1">
		3	</Property>
	<Inputs>
		<RelNode type="LogicalValues">
			<Property name="tuples">
				[{ true }]			</Property>
			<Inputs/>
		</RelNode>
	</Inputs>
</RelNode>

It's better to make 'Property' aligned.
