Enhancement: support Chinese

[cscott]

I'm using polyglossia as part of a PDF rendering backend for Wikipedia (see https://npmjs.org/package/mw-ocg-latexer). It would be nice if polyglossia had even rudimentary support for CJK languages, so I could support ko.wikipedia.org, ja.wikipedia.org, zh.wikipedia.org and embedded CJK text in the other wikis.

Note that Korean and Japanese are supported (at least rudimentally). Thus changing title.

Currently ctex is my workaround.

I tried to create ldf files for Chinese by referring Japanese ldf and tex/latex/ctex/config/ctex-name-utf8.cfg I do not speak Chinese and I'm not sure whether they are appropriate or not.

Thanks, @t-tk! As I do not speak Chinese either, we need a volunteer to audit and test these files.

I added examples of XeLaTeX & polyglossia with multilingual texts:

@t-tk, @reutenauer what do you think: shall we add Tanaka-san's gloss file and flag them experimental? This way we probably get most chance for testing and feedback.

@zepinglee in CTeX-org kindly sent a feedback: https://github.com/CTeX-org/ctex-kit/issues/639#issuecomment-1265011929 I can send pull request if you do not mind.

Excellent. Yes, please do. If you could also add documentation, it would be perfect.
