Add option "By Car" in transmission assist that changes the clutch option according to the car

Add in Assists the option to follow what the current car uses for clutch.

  • Cars with stick shifter work as if “Manual with clutch” was selected
  • Cars with sequential shifter work as if “Manual” was selected
  • I don’t recall if FM and FH has any cars that are fully automatic from factory, but if that’s the case then they would work as if “Automatic” is selected.

This is specially useful for wheel users that have both a sequential and H type shifter, as right now we either need to disable the clutch, use the clutch in cars with sequential shifters or change the assist option manually every time we change cars.

As an UI improvement, add the information of the shifter type in the car selection menu, so players don’t need to know the car or look inside it to know what type of shifter the car has.
