libata: support host-aware and host-managed ZAC devices

Byte 69 bits 0:1 in the IDENTIFY DEVICE data indicate a
host-aware ZAC device.
Host-managed ZAC devices have their own individual signature,

And whenever we detect a ZAC-compatible device we should
be displaying the zoned block characteristics VPD page.
