This changes how DebugWithDb works:

All field values are always included (useful) and thus the include_all_fields flag is removed (it was annoying).
Dependencies from those field values are ignored by salsa (useful, but potentially dangerous).
You can use #[customize(DebugWithDb)] to skip generating the impl for a given type.

I think overall this is an improvement, though it is a breaking change.
