Support wireframes for 2D meshes

[msvbg]

Objective

Wireframes are currently supported for 3D meshes using the WireframePlugin in bevy_pbr. This PR adds the same functionality for 2D meshes.

Closes #5881.

Solution

Since there's no easy way to share material implementations between 2D, 3D, and UI, this is mostly a straight copy and rename from the original plugin into bevy_sprite.

Changelog

• Added Wireframe2dPlugin and related types to support 2D wireframes.
• Added an example to demonstrate how to use 2D wireframes

The example looks very different for me. I'm only seeing lines around the shapes but no inside triangles are visible for me

[IceSentry]

Also, can you rebase on main? I think the Color changes will break some stuff

Not entirely sure why the check-bans job is failing, perhaps because I modified Cargo.toml? It seems to be complaining about duplicate lock file entries.

[alice-i-cecile]

Yep, the check-bans failure isn't your fault. It's a real-but-noisy failure that we're blocked on fixing due to version synchronization dances.

[msvbg]

I see that @IceSentry approved already, but I felt that I should use the new color types now that #12137 was merged. I added 80aea41 and 2d177ff.

I think adding it to bevy_internal should be done in a separate PR. I know it's tiny, but it makes it easier to keep track of history if it isn't mixed with unrelated things. I'm not entirely sure what the plan is for migration of bevy_color though.

Agreed. I'd like a small PR adding it to bevy_internal and exporting a prelude like the other crates. Feel free to open it @msvbg, otherwise I'll get to it in the next couple of days.

[alice-i-cecile]

I've added the new color types to bevy_internal in #12158.

[msvbg]

Rebased on top of #12158.

[SludgePhD]

This should fix #5881

[msvbg]

Oh, didn't realize we had two of these PRs. My bad for not searching properly.

[alice-i-cecile]

Looks sensible, and an important feature.

[alice-i-cecile]

@msvbg looks like there's been breaking changes on main that need to be adapted to.

[msvbg]

I'll get it fixed up.

@alice-i-cecile I resolved the problems in 7451663 and checked that the example still looks good :)
