Convert Listings in Chapter 10 to `<Listing>`

[SpectralPixel]

Finally, here is chapter 10 adapted to the new <Listing> pre-processor. I'm not sure if everything works as intended since I couldn't get mdbook to behave properly on my machine, so please check the sanity of my changes.

I also changed numberless listings (as in, they have a file name, but no number), so feel free to revert those commits if they are not yet fully functional by the time they will be merged.

Please also check all the comments I have left in commit descriptions and the issue thread for further concerns I might have about the code.

(By the way, I also fixed some conflicts while moving the commits around)

Issue #3919
