This commit adds a function that validates a DPEInstance's context array, to ensure it represents a properly-formed tree. This function will be called from caliptra rt-fw when it validates the DPE instance loaded from SRAM upon a warm reset.

This commit adds a function that validates a DPEInstance's context array, to ensure it represents a properly-formed tree. We also add functions to retrieve the current tci from a context, and get the index of a context whose locality and tci_type are equal to some parameters. These functions will be called from caliptra rt-fw when it validates the DPE instance loaded from SRAM upon a warm reset.
