[ros-diffs] [hpoussin] 14512: Add serial port enumerator driver:

Add serial port enumerator driver:
- Enumerate legacy mice
- Should also detect PnP serial devices even if they are not yet
reported
It is implemented as an upper filter for serial port driver (serial.sys)
Add corresponding registry entries
