Cycles: Replace object index hack with actual checks for SD_TRANSFORM_APPLIED

Using ones complement for detecting if transform has been applied was confusing
and led to several bugs. With this proper checks are made. Also added a few
transforms where they were missing, mostly affecting baking and displacement
when `P` is used in the shader (previously `P` was in the wrong space for
these shaders)

Cycles: Fix bump mapping to use object space when used with true displacement

Bump mapping was happening in world space while displacement happens in object
space, causing shading errors when displacement type was used with bump mapping.

To fix this the proper transforms are added to bump nodes. This is only done
for automatic bump mapping however, to avoid visual changes from other uses of
bump mapping. It would be nice to do this for all bump mapping to be consistent
but that will have to wait till we can break compatibility.

Cycles: Transform undisplaced coordinates into world space for bump shader eval

Forgot to do this, shading should be correct now for transformed objects.

Cycles microdisplacement: Improved automatic bump mapping

Object coordinates can now be used in the displacement shader and will give
correct results, where as before bump mapping was calculated from the displace
positions and resulted in incorrect shading.

This works by evaluating the shader in two parts, first bump then surface, and
setting the shader state to match what it would be if the surface was
undisplaced for the bump shader evaluation. Currently only `P` is set as if
undisplaced, but other shader variables could be set as well, such as `I` or
`time`. Since these aren't set to anything meaningful for displacement I left
them out of this patch, we can decide what to do with them separately.

Cycles: remove duplicate shader storage

Storing multiple copies of a shader was needed when the displacement method was
a mesh option and could be different for each mesh. Now that its a shader option
this is unnecessary.

Make Cycles creased subdivision match Blenders more closely

Sets vertex creases to match how Blender handles vertexes on the edge of a mesh.
There's probably more inconsistencies but I'll see about handling those later.

Move displacement options from mesh settings to material settings

Displacement is now a per material setting, which means old files will have to
be updated if they had used displacement. Cool side effect of this change is
material previews now show displacement.
