[media] rc: rc-core: Add support for encode_wakeup drivers

Browse Source 
Add support in rc-core for drivers which implement the wakeup scancode
filter by encoding the scancode using the raw IR encoders. This is by
way of rc_dev::encode_wakeup which should be set to true and
rc_dev::allowed_wakeup_protocols should be set to the raw IR encoders.

We also do not permit the mask to be set as we cannot generate IR
which would match that.
