Implemented ML utility functions to convert IO data type to name,
IO format to name and routine to get the size of an IO data type
in bytes.

v5:
* Moved the code from drivers/common/ml to lib/mldev
* Added rte_ml_io_ prefix to the functions
v2:
* Implemented common utility functions as part of the patch
* Dropped use of driver routines for data conversion functions
