- SW: Uplift of DoPlayerTurn().

Browse source 
* Set `PF2_INPUT_CAN_TURN` explicitly where `DoPlayerTurn()` would have been done within the original game.
* Uplift the turn 180 code to full Q16.16.
* Eliminate stupid input scaling so input matches that provided by the input device.
* Ticrate angle adjustments outside of the player's control still to be uplifted.
