MSVC does not define __cplusplus as >=201103 yet.
An older version of MSVC is probably sufficient, but I can't test that.

This reverts commit c7a1e5cd.

This allows assigning property values even if the property type is
unknown, e.g. when iterating over mesh properties.

This is useful for precondition checks in client code.

GeometryKernel::collect_garbage used to first perform the TopologyKernel
garbage collection, usually shrinking its vertex_deleted_ member, then
accessed it using is_deleted() with the old vertex indices.

This caused out-of-bounds memory access (made visible by
cmake -DSTL_VECTOR_CHECKS=ON) and non-fast deletion also resulted in wrong
results, the remaining vertices had wrong coordinates.

Should compile now even when properties are used that do not have an operator>>
