Force transparency & Layered windows

Force transparency is an option available under the General page of Mica Visual Studio's settings. As its description suggests, it forcefully removes the background of select elements. Disabling this readds the background to all tool windows, making their backdrop setting redundant.

Layered windows is another option available under the General page of Mica Visual Studio's settings. Enabling makes it so that child windows for any top-level window in Visual Studio receive the WS_EX_LAYERED style. This makes it so that they don't receive the chosen backdrop. This is done to fix readability in lighter-colored color themes.
