Feature request: Auto-reload controllers after changing `Settings -> Directory -> Controller Profiles`

[davidhedlund]

Description

The back button functionality is broken for some controllers using RetroArch's fallback mode. This prevents users from reload new controller profiles by:

• Navigating to Settings -> Directory -> Controller Profiles
• Go back to Main Menu -> Quit -- which is required by Android ports of RetroArch to save configuration.
• Start RetroArch again.

The way to set the back button is to manually configure the controller by following these steps:

• Go to Settings -> Input -> RetroPad Binds
• Select Port 1 Controls
• Use the options Set All Controls and Save Controller Profile

Expected behavior

The controller should automatically become active upon connecting or changing directories.

Actual behavior

When switching to a directory containing a non-default controller profile, the controller doesn't activate automatically.

Steps to reproduce the bug

• Go to Settings -> Directory -> Controller Profiles
• Select a directory with a custom controller profile (not included with RetroArch by default).
