JavaScript: Simplify flow-summary queries.

Previously, `AllConfigurations.qll` would pull in (almost) all taint
tracking configurations, which has started causing OOMEs during
compilation.

I've pruned it down to only the most interesting configurations. Since
flow summaries are experimental at this point and require a bit of manual
configuration anyway, this shouldn't be much of an issue in practice.
