uninit_drivers: : Bitmask of drivers to deinitialize.

Deinitializes drivers.

determines which drivers get deinitialized.Driver ownership - set this to true if the platform in question needs to 'own' the respective handle and therefore skip regular RetroArch driver teardown/reiniting procedure.

If to true, the 'free' function will get skipped. It is then up to the driver implementation to properly handle 'reiniting' inside the 'init' function and make sure it returns the existing handle instead of allocating and returning a pointer to a new handle.

Typically, if a driver intends to make use of this, it should set this to true at the end of its 'init' function.
