To enable CET for MSVC, only passing "/CETCOMPAT" to
the linker should be sufficient.
Enabling generation of EH Continuation (EHCONT) metadata
is additional protection and should not be necessary.
It also requires all the dependencies to be re-compiled
with EHCONT enabled, otherwise the linker will refuse
to link the obj files. However, this is rather hard
to achieve if your application depends on many 3rd-party
libraries, so to let people enable CET more freely,
we don't enable EHCONT guard by default.
Pick-to: 6.4
