add action to create Arduino package automatically #191

This repo has been stall for quite a while and there are many PRs unmerged.

This PR adds a github action file that automatically pack the repo when commit or pull request. You only need to make sure you have a release tagged as "arduinoPack", then the github action will automatically add repo zip and json into that arduinoPack release.

I hope it will simplify the process of improving code in your own repo.

You may test it on
https://github.com/DeqingSun/arduino_core_ch32/releases/download/arduinoPack/package_ch32v_index_githubActionRelease.json

Also the windows installation error has been fixed. WCHISP packed as well.

The included WCHISP was compiled with https://github.com/DeqingSun/wchisp/tree/CH375DLL64_access . So if you are using Windows, CH375 (WCH official wchisptool) and LIBUSB both work.
