[release/6.0] Ignore non-X509 certificates in SignedCms (#67462)

* Ignore non-X509 certificates in SignedCms

This allows for AttributeCertificateV1/AttributeCertificateV2/OtherCertificate
entries in the SignedCms without causing a decode error.  That data is not presented
to callers via the SignedCms object, but the behavior is consistent with SignedCms on
.NET Framework and its underlying WinCryptMsg counterpart.

* Add packaging changes for servicing
