Add rsmi_dev_target_graphics_version_get

Updates:
   - [API] rsmi_dev_target_graphics_version_get, takes
     reported value from KFD -> parses into human-readable
     values. If device does not support, returns MAX UINT64
     value and RSMI_STATUS_NOT_SUPPORTED.
     Otherwise, puts into base10 format removing
     extra 0's + putting in correct format. If user
     provides nullptr, returning RSMI_STATUS_INVALID_ARGS.
    - [Test/Example] sys_info_read updated to include
     new rsmi_dev_target_graphics_version_get tests
