CMake: Raise LINK_INTERFACE_MULTIPLICITY to 3

The internal blender library dependency loops are longer than
the default cmake settings account for. As the work in [1]
adds more dependencies where they are needed this has become
a problem.

Bumping to 3 now as it solves the immediate linker problems in
#132375 but we can bump this further in the future if needed.
