[Feature request] Add CLI argument support to custom config.
Quick summary
Currently the only way to pass cli arguments to the emulated game is by booting rpcs3 via command line/terminal. I request that a text box be added to the advanced tab of custom config where users can type the commands they wish to pass on to the emulated game.

In its current state, users cannot pass cli arguments to the emulated game that contain - as rpcs3/qt assumes them to be arguments for itself (see #8926 ), adding a text box to the advanced tab of custom config where users can type the cli arguments they want to pass to the emulated program would make using them much easier and also get around the issue mentioned above.
+1 the current implementation of passing cli arguments to games is almost completely useless since most launch parameters contain -.
