Geoffrey McRae 04fd31219c [idd] input: add mouse and keyboard IPC messages
Replace raw HID report forwarding with typed absolute mouse, relative
mouse, and keyboard messages.

Expose absolute and relative modes as separate Mouse collections because
Windows MouHID requires one X/Y motion mode per mouse device.
