Provide source code of all libraries instead of providing a static linked library

[luojia65]

By now if we need to look into what this library includes, we have to do reverse engineering works. By providing source code (or write a clean room one without reading its original source) we can get this library bottom-up in Rust compiler only without tampering with the toolchains.

Unfortunately for the time being this is fairly unlikely to happen. To be honest, I'm not aware of any open source WiFi stack, this is just the way it is currently. You can follow espressif/esp32-wifi-lib#2 for more updates. In general we try and move everything we possibly can out of the blobs that don't have to be there.

Closing, please follow the upstream issue.
