Handle indirect calls in CallGraphPropertyAnalysis (#2624)

We ignored them, which is a bad default, as typically they imply
we can call anything in the table (and the table might change).
Instead, notice indirect calls during traversal, and force the user
to decide whether to ignore them or not.

This was only an issue in PostEmscripten because the other
user, Asyncify, already had indirect call analysis because it
needed it for other things.

Fixes a bug uncovered by #2619 and fixes the current binaryen
roll.
