Integrated sort line

### Description

Almost every texteditor has a "sort line" tool. Netbeans is still missing it.
There exists an unofficial plugin:
[sort-line tools](https://github.com/netbeanslab/nb-sort-line-tools)

But I think this should be added to core. This is often useful, e.g. sorting case-statements, file-lists (in textfiles) and other stuff.

Start by reviewing the linked unofficial sort-line-tools plugin to understand the proposed behavior and how it could fit NetBeans core. Define the expected sorting options and editor entry point before implementation; done means a core sort-line tool is available for the stated text-editor use cases.
