Windows: Move building of blendthumb into the blender codebase.

Previously this was done in the deps builder due to the fact we needed
both 32 and 64 bit versions of this dll and CMAKE does not support that
in a single build folder. Now that 32 bit support has been dropped, this
can be safely moved into the codebase.
