feat(ble): Add event for non-active BLE profile changes

[snoyer]

Currently zmk_ble_active_profile_changed events are raised when the state of the active profile changes but we don't get notified if the state of any other profiles changes.
This means that, for example, the nice!view display of individual profile states (#2265) will not update if a device that is not on the active profile disconnects on its own.

This PR adds a zmk_ble_other_profile_changed (similar to the existing zmk_ble_active_profile_changed) that gets raised from the connected() and disconnected() methods when the connection is not the active one.

Does this also address #2872 similar to #2873?

According to the implementation of #2873, no, this one doesn't expose or react to the advertising state.
But according to the description of #2872, I'd say yes, it does let you know about profiles other than the active one. Would need @adolto to confirm whether they actually need the advertising details.
