vm_tools: sommelier: allow it to pass gamepads into VM

Implement a basic wayland zcr_gaming_seat_v2 protocol <-> uinput bridge
to present gamepads (game controllers) to VM.

Note that this logic does not perform extensive controller remapping;
it is not expected to work successfully with the more exotic (further
from simple HID standard) controllers.

Wayland gaming profile copied from Chrome source at
third_party/wayland-protocols/unstable/gaming-input/gaming-input-unstable-v2.xml

BUG=b:171985777
TEST=Manual w/ borealis, on hatch-kled, w/ variety of gamepads,
     and games to test button and trigger assignments are accurate.
     The controller option screen in Dead Cells is particularly
     useful as it allows almost all buttons to be mapped and tested.
     borealis board target only tested for successful build.
