It used to exit early if the function was found in `module_sp`, but now we will always scan through the whole ModuleList. And we can't change the behavior of the `ModuleList::FindFunctions` to return after the first match, because it might be not what we want in general case. Maybe I should add more generic versions of these functions taking a callback to invoke on each match instead of SymbolContextList? Something like

Can we make it configurable behind the `ModuleSearchOptions`? This is what the `FindTypes` API does via `TypeQuery` (which has a bunch of flags to configure your search, including `eFindOne`, etc.). There's already a `ModuleFunctionSearchOptions` that could be re-used for this?
