Cemu Add Apple Silicon build instructions

It builds now.

My cmake was bad and it was trying to link against arm64 libs. Terminal logs of how I resolved it

$ brew install boost   
Warning: boost 1.79.0_2 is already installed, it's just not linked.
To link this version, run:
  brew link boost
$ brew link boost
Linking /usr/local/Cellar/boost/1.79.0_2... 
Error: Could not symlink lib/cmake/Boost-1.79.0
/usr/local/lib/cmake is not writable.
$ sudo rm /usr/local/lib/cmake
$ brew link boost                                      
Linking /usr/local/Cellar/boost/1.79.0_2... 186 symlinks created.
$

To make it not crash I commented out this and it runs with controller support, good audio but graphical glitches. Saving is very slow.
