profile_manager: Implement firmware avatar selector (#205)

Adds an option to set a user's profile image from the avatars in the firmware. Background color can be changed with a color picker. Also modifies profile image saving to account for this, and as a result images are now saved as JPEG with 100% quality. Any PNG, JPEG, or BMP can now also be used in the image file picker instead of just JPEG.

Using ryujinx's implementation and other parts of the yuzu codebase for reference.
