Rework the documentation of our individual MAC implementations

We now describe parameters instead of controls.

Also, since macros like EVP_MAC_CMAC do not exist any more, we rename
the pod files from EVP_MAC_{algo}.pod to EVP_MAC-{algo}.pod.  This
allows getting the documentation like this:

    man EVP_MAC CMAC

Fixes #9709

 =head1 PARAMETER NAMES
 
+Parameters are identified by name as strings, and have an expected
+data type and maximum size.
+OpenSSL has a set of macros for parameter names it expects to see in
+its own MAC implementations.
+Here, we show all three, the OpenSSL macro for the parameter name, the
+name in string form, and a type description.

 The standard parameter names are:
 
 =over 4
 
-=item OSSL_MAC_PARAM_KEY ("key") <octet string>
+=item B<OSSL_MAC_PARAM_KEY> ("key") <octet string>
 
 Its value is the MAC key as an array of bytes.
 
 For MACs that use an underlying computation algorithm, the algorithm
 must be set first, see parameter names "algorithm" below.
 
-=item OSSL_MAC_PARAM_IV ("iv") <octet string>
+=item B<OSSL_MAC_PARAM_IV> ("iv") <octet string>
 
 Some MAC implementations require an IV, this parameter sets the IV.
 
-=item OSSL_MAC_PARAM_CUSTOM ("custom") <octet string>
+=item B<OSSL_MAC_PARAM_CUSTOM> ("custom") <octet string>
 
 Some MAC implementations (KMAC, BLAKE2) accept a Customization String,
 this parameter sets the Customization String. The default value is the
 empty string.
 
-=item OSSL_MAC_PARAM_SALT ("salt") <octet string>
+=item B<OSSL_MAC_PARAM_SALT> ("salt") <octet string>
 
 This option is used by BLAKE2 MAC.
 
-=item OSSL_MAC_PARAM_XOF ("xof") <int>
+=item B<OSSL_MAC_PARAM_XOF> ("xof") <int>
 
 It's a simple flag, the value 0 or 1 are expected.
 
 This option is used by KMAC.
 
-=item OSSL_MAC_PARAM_FLAGS ("flags") <int>
+=item B<OSSL_MAC_PARAM_FLAGS> ("flags") <int>
 
 These will set the MAC flags to the given numbers.
 Some MACs do not support this option.

-
-Support for computing KMAC MACs through the B<EVP_MAC> API.
-
-=head2 Numeric identity
-
-B<EVP_MAC_KMAC128> and B<EVP_MAC_KMAC256> are the numeric identities for this
