Vincent Palatin 5dcff8b079 g: add chip unique id generation ...

Implement system_get_chip_unique_id() for the g hardware.
It includes the hardware revision, the chip device id and
the read-only key id.
The key-id is included because this unique id is used as serial number
inside certificates and for security reason, we want a different id if
the RO has changed (e.g Node locked firmware).
The id is also 32-byte long for convenience reason when used for
certificates, but the high 16 bytes are currently zeros.

BUG=b:35545754
TEST=dump the x.509 individual attestation certificate which includes
the unique id as serial number.
