signing.bbclass: remove signing_import_cert_chain_from_pem

With the now available set|get|has_ca functions to establish a CA link
between roles during their import, the
signing_import_cert_chain_from_pem can now be removed.  As it had the
shortcoming of dynamically creating roles, which are harder to handle
then the manually/specifically setup CA roles.

This effectively reverts:
