Pass tracer to SourceLoader to fix tracing (#5833)

The `SourceLoader` emits traces under the `"import-resolution"` namespace. During the refactor in d2ac995, we stopped passing the `tracer` to the `SourceLoader` so those traces weren't happening. This appear to be a bug, as `LoadSourceOptions` has a field for `tracer`.
