uefi: Add safe EFI_USB_IO_PROTOCOL bindings

[JarlEvanson]

Add a safe wrapper around the EFI_USB_IO_PROTOCOL.

This adds wrappers around the synchronous USB transfers, acquiring the USB descriptors, and resetting the USB interface.

Relies on #1626.

Checklist

• Sensible git history (for example, squash "typo" or "fix" commits). See the Rewriting History guide for help.
• Update the changelog (if necessary)

LGTM but can you please add an integration test? If needed, attach any USB device to QEMU. Not sure what's the best way, but I suppose you have a better understanding of USB right now than me.

Do you see an opportunity for an integration test?

[JarlEvanson]

I can do that.

Testing the descriptor and reset functions should be easy, but testing the transfer functions will probably require implementing some of a USB device driver. Furthermore, testing the USB isochronous transfers would require a audio or video device, which does not appear to be easily available on QEMU.

I probably won't get around to it until Thursday.

[JarlEvanson]

I have added integration testing for the descriptor acquisition functions and the control transfers.

I do not intend to test bulk, interrupt, or isochronous transfers because testing those seem to require writing part of a USB device driver.

Thanks for your work! I left a few remarks, otherwise LGTM

[JarlEvanson]

I've resolved your requests and cleaned up the code a little.
