Add support for device.wake InputDevice Property

This change adds support for a device.wake InputDevice property. This
property can be set to "1" by an InputDevice's IDC file, and the system
would read that and sets wake flags (if applicable) to the events
generated by the InputDevice.

Bug: 289118119
Test: added "device.wake = 1" to a rotary-encoder IDC, and verified that
the wake flag is sent to the WM policy
