Remove bad storage hacks of old transform manipulators

Got rid of Scene.twcent, Scene.twmin, Scene.twmax, RegionView3D.twmat, RegionView3D.twdrawflag, RegionView3D.tw_idot, TransInfo.mat, TransInfo.vec.
Also cleaned-up variable and define names.

Decided to completely remove the struct members without doing proper file conversion for non-runtime ones. That will cause minor compatibility breakage but that's okay for 2.8.
