gsm: add osmo_mobile_identity_decode_from_l3_buf()

We have osmo_mobile_identity_decode_from_l3(), which takes a msgb as
argument, and decodes msg->l3h. Not all callers have their data in this
form. Offer a more flexible API for the same decoding.

For example, before the new function, osmo-hnbgw, which extracts a NAS
PDU from asn.1 packed data for CN pooling, would allocate a new msgb and
copy the NAS data just to pass a data pointer as argument.
