core: hid: Post kraken cleanup

Allows us to be more explicit with the representation of button states and use the provided bit manipulation operators

We were previously truncating this to a u32 as there were no known buttons that used the full 64 bits of this type. Fix this now that we know they are used.

This represents a bitmask for all pressed buttons

This also moves the use of DisableConfiguration to the destructor.

Add missing pixel format mapping

qt_controller: Fix input when the controller applet is ignored

TextureCache: Eliminate format deduction as full depth conversion has been supported.

Core: Stub services and functions needed for checkpoint
