Editor time auto-updating of FSongData::CachedMaximumSongDuration

Struct FSongData includes the following field:

/** Maximum song duration cached from the AkAudioEvent during cooking to allow accessing that information on Dedicated Servers */
UPROPERTY()
	float CachedMaximumSongDuration{0.0f};

This property is supposed to be populated at build time, but for some reason in 1.1 editor it is left as 0. This partially breaks the BoomBox - the tape cannot switch to the next song, instead it's playback indicator is set to 0:00 once the AKAudioEvent ends.

I was able to quickly hack around it by making this property editable and populating it manually, but a cleaner way would be to auto-populate at build time. There is a void CachePlaylistSongDurations(class FWwiseProjectDatabase* InProjectDatabase); callback of FGTapeData, which I guess is supposed to be used exactly for that.

In 1.0 this property wasn't present yet (based on the tape uasset for 1.0).

Start by tracing FGTapeData::CachePlaylistSongDurations(class FWwiseProjectDatabase* InProjectDatabase) and how it reaches FSongData::CachedMaximumSongDuration during cooking. Reproduce the editor 1.1 build or cook, then verify that the cached duration is populated and the BoomBox tape advances to the next song instead of resetting to 0:00.
