[crypto] Hold CMS message as a single ASN.1 object
Reduce the number of dynamic allocations required to parse a CMS
message by retaining the ASN.1 cursor returned from image_asn1() for
the lifetime of the CMS message. This allows embedded ASN.1 cursors
to be used for parsed objects within the message, such as embedded
signatures.
