Improve Scheme generation

- Generate a scheme containing all indexer targets as buildable
  references. This gives Xcode enough information to index indexer
  targets using the active ARCH instead of x86_64.
- No longer generate runnable schemes for library and test targets
  Test targets are still testable, but not runnable. Similarly,
  library targets are still buildable, but not runnable.
