usb: replace libusb with Rust usb_util library
Drop the dependency on libusb and reimplement the host USB backend using usb_sys to wrap the Linux usbdevfs ioctls. This allows sandboxing to work without any dependency on libusb patches, and it gives us the flexibility to modify and update the USB backend without depending on an external third-party library. BUG=chromium:987833 TEST=`adb logcat` on nami with Nexus 5 attached TEST=deploy app to phone with Android Studio TEST=Run EdgeTPU USB accelerator demo (including DFU mode transition) Cq-Depend: chromium:1773695 Change-Id: I4321c2b6142caac15f48f197795a37d59d268831 Signed-off-by: Daniel Verkamp <dverkamp@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/1783601 Reviewed-by: Zach Reizner <zachr@chromium.org> Tested-by: kokoro <noreply+kokoro@google.com>
