[Maintenance] [th04/th05] Dialog: Start a new translation unit with shared code Thanks to the required word alignment of the `switch` jump table in TH05's dialog_op(), we do in fact have to slice dialog code into exactly two* translation units. Three might have been better because we would have only needed to compile this shared code once, but TH05 also has one exclusive function in the area covered by this new shared translation unit anyway. At least we can meaningfully share the actual source files between games here. * With an additional one at the end for now, because I absolutely had to RE that EMS code in late 2021, but we'll catch up with that one in the end.
