Subject: [PATCH] Documentation: Add rule about "east const" to CodingStyle.md

with this in mind, and convert old code as we go.

+[](#east-const) Use "east const" style where `const` is written on the right side of the type being qualified. See [this article](https://mariusbancila.ro/blog/2018/11/23/join-the-east-const-revolution/) for more information about east const.
