Setting up RetroArch on Raspberry Pi 4 and building emulator cores

Guide for myself and others to get RetroArch running on the new Raspberry Pi 4 while projects like RetroPie get an image out for the rpi4.
Disclaimer: I am not an expert and this may not be the most optimal build possible, but it works.

Inspiration taken from:

• This gist showing the basic steps for building and configuring for raspberry pi 3. I'm new to Raspberry Pi and RetroArch myself so this was super helpful and I recommend looking through it.

• This Reddit post showing the performanc gains over the pi 3b+

// There are two step in middleware processing.
// 1. Middleware initialization, middleware factory get called with
//    next service in chain as parameter.
// 2. Middleware's call method get called with normal request.
