Fix #3110

This is still a draft, but I'm interested in feedback on the approach. It feels a little clunky that you now cannot assume invariant of RuntimePackAsset non-empty == self-contained, and that I had to run a separate conflict resolution pass in the crossgen + fdd. So I'm interested in other ideas. I don't think this is terrible, though, so if you think this isn't too bad, I'll probably stick with it. Working on tests and fixing the error message still.

We had been lumping #3109 and #3110 together in discussions, but they're actually quite separate. This only fixes #3110. I will move on the #3109 next once this is out of draft.

Can we now delete this:

Line 87 in fce5096

// TEMP LOGIC - SDK Should provide correct list - When fixing https://github.com/dotnet/sdk/issues/3110, delete

Can we now delete this:

No. We need #3109 for that. It appears the comment is referencing the wrong bug. I'll fix that.

Went ahead and marked this ready for review. If we decide to take a fundamentally different approach, I'll close and start fresh on that.

The _CreateR2RSymbols target needs to be fixed to use the _ReadyToRunImplementationAssemblies list
