overlay_dialog: Add an overlay text dialog that accepts controller input
An OverlayDialog is an interactive dialog that accepts controller input (while a game is running) This dialog attempts to replicate the look and feel of the Nintendo Switch's overlay dialogs and provide some extra features such as embedding HTML/Rich Text content in a QTextBrowser. The OverlayDialog provides 2 modes: one to embed regular text into a QLabel and another to embed HTML/Rich Text content into a QTextBrowser. Co-authored-by: Its-Rei <kupfel@gmail.com>
