cmd/go/internal/modload: refactor pathInModuleCache

I found the control flow of this function a bit tricky to reason about
due to nesting and interaction between conditions and iteration. This
change factors out a helper function that can return early instead of
mixing conditionals and 'continue' statements.

Also remove the (unused) ModuleUsedDirectly function.

For #36460
