COMP: Suppress deprecated warnings in MSVC wrapping builds

Add /wd4996 to MSVC compile flags for SWIG-generated Python wrapper
targets. This suppresses C4996 warnings triggered by deprecated
VariableLengthVector::AllocateElements calls in auto-generated wrapper
code. GCC/Clang wrapping builds already suppress all warnings with -w.
