Add NinjaOutputsWriter class

Implement a new class that can be used to generate a JSON
file containing an object mapping GN label strings to
list of corresponding Ninja output paths (including stamp
files).

This will be used to implement a new `gn gen` option.
The output can be used by GN clients to quickly convert
between GN labels and Ninja targets.

This is done through the following changes:

- NinjaTargetWriter gets new methods to write output
  files to the build plan, and record the
  corresponding OutputFile values (without Ninja
  escaping) separately if needed.

- All NinjaTargetWriter sub-classes are updated to
  call WriteOutput() or WriteOutputs() when adding
  Ninja output paths to the generated .ninja_files, instead
  of calling path_outputs_.WriteFile() directly.
