Revert "Make shared libraries be able to link to MSVC static runtime libraries, so that VC runtime is not required." (#6914)

This reverts commit 129a7c87. We are
seeing the following error when building Python release artifacts in Windows:
" error LNK2038: mismatch detected for 'RuntimeLibrary': value
'MD_DynamicRelease' doesn't match value 'MT_StaticRelease' in
descriptor.obj".
