citra_qt/applets/swkbd: QtKeyboard and misc fixes
* Addressed comments and removed the applet interface

* swkbd: address @lioncash's comments

* core: more fixes

** Moved registered_swkbd to System

** Removed an usused virtual

** Removed functionality of DrawScreenKeyboard

** Removed src/core/settings.h change

* swkbd: address @lioncash's 2nd review
