Move SPECIAL_FUNCTION from .kcm to .idc files
Currently, the only use of device-specific .kcm files is to specify
SPECIAL_FUNCTION flag (meaning that this keyboard is only used to
perform system control functions and not for typing).
Instead of adding a special .kcm file, use .idc files with se
keyboard.specialFunction = 1 to achieve the same functionality. This
allows the removal of all device-specific .kcm files.
The .kcm functionality will remain in P (with a warning). The
functionality will be removed in Q.
