Rewrite commands and add new command type (#12233)

Browse Source 
* (OSX non-Metal build) Set disable execute page protection

* Rewrite commands and add new command type

This moves commands to a separate file and creates a consistent
interface for them. It is now possible to use multiple command
interfaces simultaneously (stdin, network and UDS).
Implemented a new interface for Lakka, UDS based (so Linux only). This
allow other Lakka servies to send certain commands to Retroarch in a
secure and reliable way.
