Add a new attribute to the builder with an arbitrary value.
Unconditionally adds a new attribute, even if one with the same attr_type already exists.
Ownership of the value memory is taken by the builder, may be reallocated, and is eventually freed with
g_free. The memory must have been allocated using the standard GLib memory allocation routines.
null may be specified for the value argument, in which case an empty attribute is created. [constINVALID
] may be specified for the length, in which case an invalid attribute is created in the PKCS#11 style.
