enables Arbitrary Mipmap Detection.

These games greatly benefit from CPU Culling, and there isn't much reason
not to just blanket enable it for all users. There is no case where you'd
want it disabled.
This will avoid effects being unexpectedly broken in these games if the user disables the option globally. This list is by no means comprehensive, these are just the games I could confirm use custom mipmaps.
