TitleMetadataTask: use a struct instead of a vector

Browse source 
The struct has been typedef'd as TitleApplicationMetadataInfo. It holds the pointer to the array returned by titleGetApplicationMetadataEntries(), as well as the number of elements available in the array.

There's no point in populating a vector when we already have an array we can work with.
