Skip writing ninja file for module with a cache hit during incremental build.

This is just the first change, many more will come to make this feature
really work. The main changes included here are:

1. Skip the writing of ninja file if a module has a cache hit.
2. Handle the case where a skipped module doesn't have the build defs
   info for the OrderOnlyStrings dedup logic to work by caching the
   missing info.
