[docs/makefile] Copy figures also for single targets

[LukasP46]

Hey all,
as I only want to generate html, I added

• the figures-copy as target
• dependencies on it for the html targets
• targets for folders and dependencies on it

I would welcome if someone could test if I broke the other targets as I cannot evaluate it currently.

I found a bug in the doxygen artifact: neorv32_logo_riscv.png and neorv32_processor.png are missing for the md_README.html. I'll fix it by copying all images to the acording folder, although there are some resources that will never be used. The other two methods would be to put the individual files in the makefile - no overhead, but needs to be maintained, or by automatically determining which images are needed - which seems overkill.

Hey @LukasP46.

Thanks for the update / cleanup!

Seems to work on my side.

Thanks for fixing!

I agree, this seems to be an overkill.

So I think this is ready for merging, right?
