[#14437] Modifier Stack Refactor

Browse Source 
patch by Ben Batt (artificer)

Updated patch for 6 or so modifiers added since the patch was written.

- tested with CMake and SCons
- fixed one error were flags were being added to the fluids type.
- remove BKE_simple_deform.h, simple_deform.c, move functions into MOD_simpledeform.c since there were problems with circular deps.
- moved some fluid and boolean functions used by modifiers too.
