Adapt python modules to new registration method

Cycles: Remove old non-optimized triangle intersection function

It is unused now and if we want similar function we should use
Pluecker intersection which is same performance with SSE optimization
but which is more watertight.

Cycles: Remove unused macro

Cycles: Use SSE-optimized version of triangle intersection for motion triangles

The title says it all actually. Gives up to 10% speedup on test scenes here
on i7-6800K.

Render times on GPU are unreliable here, but there might be some slowdown
caused by watertight nature of intersections.

Cycles: Fix speed regression on GPU

Avoid construction of temporary array and make utility function force-inlined.
Additionally avoid calling float4_to_float3 twice.

This brings render times to the same values as before current patch series.

Cycles: Use utility function for SSS triangle intersection

This effectively de-duplicates triangle intersection logic implemented
for both regular triangle and SSS triangle.

Cycles: Move watertight triangle intersection to an utility file

This way the code can be reused more easily.

Cycles: Move triangle intersection precalc to an util file

This is a preparation work for the followup commit which wil l move
remaining parts of Woop intersection logic to an utility file.

Doing it as a separate commit to keep changes more atomic and easier
to bisect when/if needed.

Cycles: Cleanup, move utility function to utility file

Was an old TODO, this function is handy for some math utilities as well.

Cycles: Cleanup, code style and comments

Cycles: Move intersection math to own header file

There are following benefits:

- Modifying intersection algorithm will not cause so much re-compilation.
- It works around header dependency hell and allows us to use vectorization
types much easier in there.

Cycles: Cleanup, inline AVX register construction from kernel global data

Currently should be no functional changes, preparing for some upcoming refactor.

Cycles: Cleanup, remove unused function
