isStandalone property: remove dependency on pretty-print

Summary

Change the behavior of the isStandalone property so that it takes effect regardless of the settings of the pretty-print property.

Problem

The new implementation specific property isStandalone added through JDK-8249867 required the property format-pretty-print to be true. However, there are cases where applications want the serializer to produce an output with a newline after the header but without setting the pretty-print property.

Solution

Remove the dependency on the pretty-print property.

Specification

In the implementation note of the module summary (java.xml/module-info.java), specifically in table Features and Properties, remove "when the property format-pretty-print is set to true" from the property description, thus changing it from:

indicates that the serializer should treat the output as a standalone document. The property can be used to ensure a newline is written after the XML declaration when the property format-pretty-print is set to true. Unlike the property xml-declaration, this property does not have an effect on whether an XML declaration should be written out.
