serialisation: Add a built-in base provider.

Move the libcrypto serialisation functionality into a place where it can
be provided at some point. The serialisation still remains native in the
default provider.

Add additional code to the list command to display what kind of serialisation
each entry is capable of.

Having the FIPS provider auto load the base provider is a future
(but necessary) enhancement.

+
+The OpenSSL base provider supplies the serialization for OpenSSL's

+

+
+The implementations in this provider specifically have this property

+
+=item "provider=base"
+

+
+It may be used in a property query string with fetching functions.

+It isn't mandatory to query for this property, except to make sure to get
+implementations of this provider and none other.

+
+=item "type=parameters"
+
+=item "type=private"
+
+=item "type=public"
+
+=back
+
+These may be used in a property query string with fetching functions to select
+which data are to be serialized.  Either the private key material, the public
+key material or the domain parameters can be selected.

+
+These may be used in a property query string with fetching functions to select
+the serialization output format.  Either the DER, PEM and plaintext are
+currently permitted.

+The OpenSSL base provider supports these operations and algorithms:

+
+In addition to "provider=base", some of these serializers define the
+property "fips=yes", to allow them to be used together with the FIPS
+provider.
