Add floooh/kc85.zig and floooh/pacman.zig

[floooh]

Adds my KC85 emulator project and a simple Pacman clone written in Zig:

• https://github.com/floooh/kc85.zig
• https://github.com/floooh/pacman.zig

Also, I was wondering if it makes sense to add my Sokol library bindings to the list, but didn't know what section would be best: https://github.com/floooh/sokol-zig. Please advice if this fits into the list at all and where to add :)

Added to my mantained fork, including sokol-zig.
