Raw access to trusted application secure storage

This change provides basics for creating, reading and deleting an
object in a TA secure storage.

The TA implementation shows how to use the GPD TEE Internal Core API
for some basic data persistent object manipulations.

A TA command allows to create an object in the TA secure storage.
A TA command allows to read an object in the TA secure storage.
A TA command allows to delete an object from the TA secure storage.

This example does not cover all the possibilities of secure storage API
provided to TAs: seeking into a object data stream, manipulating
key material objects instead of raw data objects, etc.
