build,win: restore vcbuild TAG functionality

--tag needs to be set after `getnodeversion` because TAG is defined in
there when DISTTYPE is not "release", setting it before `getnodeversion`
leads to --tag not being passed down in to `configure` and
src/node_version.h setting it as `-pre` by default. This change restores
the functionality that properly sets the TAG for nightlies, rc builds
and other custom build types.
