RIOT ieee802154/submac: calculate symbol time on demand

Contribution description

This moves the ACK timeout/CSMA backoff period calculation from the at86rf215 driver to the radio HAL so it can be re-used by other IEEE 802.15.4g drivers.

To do so the ieee802154_phy_conf_t structure is extended depending on the used modulation. This allows to add alternative modulations with different properties (e.g. #19172).

Testing procedure

Currently there is no driver that makes use of this.

This seems to need some MAYBE_UNUSED being sprinkled over some function declarations.

Does this need any more testing?
