Undo: turn dive- and trip-fields into flags

The divesEdited signal sends the changed field as a parameter.
Since some undo-commands change multiple fields, this led to
numerous signals for a single command. This in turn would lead
to multiple profile-reloads and statistic recalculations.

Therefore, turn the enum into a bitfield. For simplicity,
provide a constructor that takes classical flags and turns
them into the bitfield. This is necessary because C-style
named initialization is only supported on C++20 onward!

Is this somewhat overengineered? Yes, maybe.
