Cleanup: Move vfx code and solve VFX order

All the code moved to vfx module and now the VFX modifiers are evaluated in the same order defined in the interface. Before, the order was always the same and did not use the interface order.

Cleanup: Define variable using #define

Cleanup: Remove redundant object parameter for VFX

Cleanup: Remove object index parameter for vfx

Cleanup: More work to structure code

Cleanup. Create framebuffers in separate function

Cleanup: Create shaders in a separate function

Fix modifier freeing code re. ID refcounting.

Free code should not handle ID refcounting at all. This has to be done
at higher level, since in some case we want to free (temp) data that
actually did not refcount at all its IDs.

This change seems to be working OK, but as usual in that area, only
lots of testing in real-case situation will say whether there are some
hidden bugs or not.

Tweak ID->tag reset on file load (no visible change expected!).

Issue was, *some* IDs (like infamous nodetrees from materials etc.)
would not go through the 'main' read_libblock() func, so their tags were
never reset.

So now, we ensure direct_link_id() always clear the tags, and move
setting them in read_libblock() after the call to direct_link_id().

Needed for depsgraph, but general healthier fix actually.
