📄 Description

As a preliminary step to toys-to-life emulation, the goal of this PR is to implement a polymorphic USB backend class that shims all necessary functions for toys-to-life games to use emulated devices. This doesn't actually emulate any of the devices as of yet, I think it would be more fitting to leave that to @deReeperJosh, who previously contributed this feature to the other emulators.
