gfx/Fonts: Remove unused chinese fonts

It only has 27 characters, which as far as I can tell are useless for actual chinese text.

Copying the list of characters in the same order of font24CN.c into google trans gives out this almost meaningful message:

Hello, Microsoft Yahei, the corresponding dot matrix for this font is Raspberry Pi Aabc Micro Snow Electronics

Looks good to me! Thanks for keeping our codebase clean.

However, I'm only a bot - so a human will still have to approve this request.
