HID: bpf: allow to inject HID event from BPF

Browse source

It can be interesting to inject events from BPF as if the event were
to come from the device.
For example, some multitouch devices do not all the time send a proximity
out event, and we might want to send it for the physical device.

Compared to uhid, we can now inject events on any physical device, not
just uhid virtual ones.
