put every include before every import

A header first pulled in through an imported module's global module
fragment leaves no include guard in the importing unit - macros do not
cross a module boundary - so a later textual include parses it again and
MSVC rejects the redefinition. Redoes the betterRenderer sweep with
placement that stays out of #if blocks, which is where the previous one
dropped <fstream> and broke nvrenderer_d3d12.cpp.
