fix(gpt): use DC CIGDPAPA when MTE2 is implemented
Use cache clean and invalidate of data and allocation tags by PA to PoPA
maintenance instruction (dc cigdpapa) in the GPT library upon changing
the PAS for a memory region. This is required to flush allocation tags
when MTE2 (and above) is implemented.
