Huge refactor of the Driveboard:

Browse source 
-Separate each possible boards (wheel, joystick, skipad, billboard).
-Defined a Driveboard type in Games.xml for each games.
-Due to the refactoring, Driveboard Savestates have changed (a common base data + a specific board data are saved).
-Backwards compatibility with previous save states is maintained.
-Driveboard rom section is no longer required anymore. This disables Driveboard emulation in case the rom is not found.
-Added Billboard emulation (vf3, vs2, fvipers2, von2). 7 segments and lamps Outputs are redirected to Supermodel outputs.
-Changes project to C++ 17 standard.

* DriveBoard.cpp
*
* Implementation of the CDriveBoard class: drive board (force feedback)
* emulation.
*
* NOTE: Simulation does not yet work. Drive board ROMs are required.
*
* State Management:
* -----------------
* - IsAttached: This indicates whether the drive board is present for the game
* and should be emulated, if possible. It is determined by whether a ROM was
* passed to the initializer. Entirely simulated implementations of the drive
* board should still take a ROM, even if it contains no data. The attached
* should be set only *once* at initialization and preferably by the base
* CDriveBoard class. Do not change this flag during run-time!
* - Disabled: This state indicates emulation should not proceed. Force
* feedback must be completely halted. This flag is used only to disable the
* board due to run-time errors and must *not* be re-enabled. It must not be
* used to "temporarily" disable the board. Only the Reset() method may
* enable emulation and then only if the board is attached. A valid reason
* for disabling the board during run-time is e.g., if a loaded save state is
* incompatible (wrong format or because it was saved while the board was
* disabled, rendering its state data invalid).
* - IsDisabled: This method is used internally only and should be used to test
* whether emulation should occur. It is the combination of attachment and
* enabled state.
* - Disable: Use this to disable the board. Drive board implementations should
* override this to send stop commands to force feedback motors and then call
* CDriveBoard::Disable() to update the disabled flag.
