peter klausler 92a5419786 [flang] Support multiple CookedSource instances
These are owned by an instance of a new class AllCookedSources.

This removes the need for a Scope to own a string containing
a module's cooked source stream, and will enable errors to be
emitted when parsing module files in the future.
