APPS: Replace the use of OBJ_nid2ln() with name or description calls

APPS: Replace the use of OBJ_nid2ln() with name or description calls

With new provided algorithms added, we'd rather rely on the names and
descriptions that we get from the providers.

Specifically with the 'openssl list' command, we now display the
description of all algorithms.  For '-public-key-algorithms', we
additionally print key type information a bit more like we do for
legacy methods.

We also add descriptions to all our keymgmt functions, because the
built in EVP_PKEY_ASN1_METHODs had them.
