Implement console specific Settings class

[acmeplus]

Currently the Settings class manages all the settings for the different elements whether those are general or console specific (volume, brightness, fps, theme selection, etc.).

Desired implementation:

• The parent Settings class should implement pure virtual functions for any settings that may have platform specific implementation. For instance, brightness control may be different in the RG35XX than it is in the M17.
• The console specific Settings class will override the console specific settings and change the default implementation
