Pack should glob result of publish or not

Need further discussion

I think I suggested ResolvedFileToPublish previously but having doubts now. It could by PreserveNewest with some modification already done in the publish output or users could have targets with stuff in there. (or even post-built steps using xcopy execute).
The most "correct" but also slowest would be to do the same as the web sdk does for publishing - clean an intermediate directory and publish to it, then use a glob to harvest this clean publish. e.g. like #1846 (comment)

ResolvedFileToPublish by the property name should be the right one to use. However in MSBuild the author can always override things. At the same time Publish folder could have similar issue when unexpected item being dropped to Publish folder. At lease we can avoid one globing, which is a big perf cost.

Close for now
