Added Draw Distance option to Display settings

[Mode8fx]

This adds a new setting to the Display menu that lets you change the draw distance to anywhere between 0.5x and 5x the original game's draw distance, in 10% increments. This should be useful for weaker devices like a Raspberry Pi that can't handle the NODRAWINGDISTANCE build option. This option does not appear in the menu if NODRAWINGDISTANCE is used.

This was implemented by adding a new variable that is multiplied with every instance where an object's distance to Mario is compared in an "#ifndef NODRAWINGDISTANCE" define. Additionally, all of the original draw distances are divided by 100 since 100 represents a normal draw distance. The end result is the same, but this removes the need for continuous float multiplication where applicable (example: "2400.0f" becomes "24 * configDrawDistance", where configDrawDistance is an integer between 50 and 500, default=100).

Maybe it would be a good idea to eliminate NODRAWINGDISTANCE entirely later if we merge this. That could be its own separate PR though.

[Mode8fx]

Maybe, but it's not really hurting anything, either.

Nice I wanted something like this, because when you add a lot of high poly models with NODRAWINGDISTANCE sometimes it lags. What if the distance is set automatically based on the performance? it's posible?

Maybe you could check what entities are in a level when you load it and how many polygons exist among these entities, then scale according to your hardware? No idea, maybe someone with a better understanding of loading that stuff could look into it.
