HID: quirks: add support for Legion Go dual dinput modes

The Legion Go features detachable controllers which support a dual
dinput mode. In this mode, the controllers appear under a single HID
device with two applications.

Currently, both controllers appear under the same event device, causing
their controls to be mixed up. This patch separates the two so that
they can be used independently.

In addition, the latest firmware update for the Legion Go swaps the IDs
to the ones used by the Legion Go 2, so add those IDs as well.
