datapath-windows: Support to selectively compile targets
Adds support to selectively compile kernel driver for
target versions. This is useful when environments to
compile for all targets might not be available on the
user's machine, or if the user wants to only compile
some targets selectively.
Also once appveyor has support to build Win10 targets,
we will not pass the "--with-vstudiotargetver" to the
configure script.
