lokdialog: Allow closing the Format Cell dialogs in any order.

Includes also lots of infrastructural changes, making the
conversion of the rest of the dialogs much easier.

StartExecuteAsync should be used in-place of StartExecuteModal
and the latter removed from the code-base incrementally. More
common code from Dialog::Execute should be moved to
ImplStartExecuteModal in a next step, as this is used more widely.
