Fix race condition when using validations

To allow a validation B on a target A to depend on A I previously
decoupled resolution of A from resolution of B. While testing this with
fuchsia I ran into a race condition where target A would be written
while B was not fully resolved. This caused the Ninja file to contain
garbled output for B.

This CL decouples resolution and writing so that a target A can resolve
but waits with writing until all its validations are resolved too.
