Add basic word wrapping

[ffreyer]

Description

This adds word_wrap_width as an attribute for text, which sets a limit for the size of a line. If a word (currently anything between two spaces with no newline in between) overflows this limit, a newline is inserted before it to wrap it to the next line.

Example (which is also the test I added):

Type of change

• New feature (non-breaking change which adds functionality)

Checklist

• Added an entry in NEWS.md (for new features and breaking changes)
• Added or changed relevant sections in the documentation
• Added reference image tests for new plotting functions, recipes, visual options, etc.

I think this could be nice with Label. Instead of having it resize to "fit" long text, the text could be wrapped to a region fitting the Label instead. Could also be helpful for Axis titles, x and y labels, etc. Related: #757

Tests only failed because there is no refimage for new test

I added word_wrap::Bool to Label now. Setting it to false (default) gives the old behavior. With word_wrap = true the Label uses the suggested width as its width and wraps text to fit (height is derived). The refimage test looks like this:

Moved some stuff around to avoid creating a second GlyphCollection and got this to work for latex strings. (At least strings with mostly text.) New first refimage:

Hi,

I have implemented the same feature here (although in a hacky way) https://github.com/fatteneder/MakieSlides.jl
This is just a proof-of-principle implementation to see whether we can use Makie.jl and its layouting functionality as the building blocks for a new presentation/slideshow engine with Markdown syntax (a la reveal.js and Marpit etc, but without the html/css madness :) The initial idea was mentioned on Zulip.
In case you wanna take a look please check the test folder for examples, the ones in examples are broken right now.

The reference image you added already goes into the same direction with what I want to do. So I very much support this PR for Makie native line wrapping support. Please let me know if I can be of any help here.

Funnily enough I also worked on this for presentations. Though I didn't end up using it myself.

This is my attempt: https://github.com/ffreyer/MakiePresentation.jl It requires #1818

That's funny. If you want we can join forces :)

For the next 2 weeks I want to keep my package (more or less) as is because I have a presentarion planned with it and I don't want to break it. After that I'd be happy to merge them.

All test errors are because of the missing refimg for the new test, so this is ready to be merged again
