edge: Add bitvec based DL window updating methods

The current methods are based on the GRPS specific RBB and SSN values
and formats which are not compatible with EGPRS.

Add a second set of similar methods with the same semantics but
which are based on a bitvec and the first BSN instead.

The following methods are affected:

- gprs_rlc_dl_window::update
- gprs_rlcmac_dl_tbf::rcvd_dl_ack
- gprs_rlcmac_dl_tbf::update_window
