xinput: RawEvents: support lists axisvalues and axisvalues_raw

Support the lists axisvalues and axisvalues_raw in RawEvents.
These are RawKeyPress, RawButtonPress, RawTouchBegin and their eventcopies.

The length of both lists is determined by the number of bits set in the
list valuator_mask. This is solved in the same way as for event KeyPress.
