target/adiv5: probe MEM-AP supported transfer sizes including large data

Based on Daniel Goehring's [1] and Peter Collingbourne's [2] work.

Probe for support of 8, 16 bit and if the large data extension is available
also probe for 64, 128 and 256 bit operations.
Probe for the ability of packing 8 and 16 bit data
(formerly probed in mem_ap_init()). The probe is integrated to
mem_ap_read/write() routines and takes place just before the first memory
access of the specific size.

Add 64, 128 and 256 bit MEM-AP read/writes.

Introduce specific error codes for unsupported transfer size
and for unsupported packing.
