Fix #7793: Do not expose internal input API (#7794)
* Fixed GetFileInformationByHandle initializers

* Fix #7793: Do not expose internal input API

Slow-Path input uses UINT16 for scancodes on wire, but only the
lower byte is actually used. (the extended fields are sent in
keyboardFlags field)
Hide this implementation detail and adjust the API to use UINT8
for the code instead just like the corresponding Fast-Path PDU

* Added a warning for problematic slow path keyCodes
