MLK-19801: Add tag functionality

Add functions to tag an object with metadata(configuration).

It is possible to:
 - create metadata:
	- init_tag_object_header
	- init_blackey_conf
	- set_tag_object_conf
 - retrieve metadata:
	- get_tag_object_conf
	- get_blackey_conf

The API expects an object to be a space a memory
with an address and a size.

The implementation of the tag is currently exposed
but users shouldn't access it directly, they should
use the functions provided.
