Add native full_testcase_name_map for clean test names

Introduces a new `full_testcase_name_map` parameter
that stores filtered test case names during cartesian
config parsing, removing type_specific and io-*
provider prefixes natively using variant label attributes.

Changes:
 - Add full_testcase_name_map generation in
    cartesian_config.py
 - Update discovery.py to use a native map
 - Add full_testcase_name_map to reserved keys
