[Debug Tools] Always use includeHooksSource option (#28309)

This option was added defensively but it's not needed. There's no cost
to including it always.

I suspect this optional was added mainly to avoid needing to update
tests. That's not a reason to have an unnecessary public API though.

We have a praxis for dealing with source location in tests to avoid them
failing tests. I also ported them to inline snapshots so that additions
to the protocol isn't such a pain.
