Consider target outputs as existing files in `gn suggest`.

When suggesting dependency changes via `gn suggest`, a file in the output
directory is considered to exist if it is output by a target in the build
graph, even if it has not yet been written to disk.

This enables suggesting dependencies on targets that produce generated
header files. When multiple targets are found (e.g. an action target
producing the file and a source_set target exposing it in headers), we
prefer the consumer target to avoid suggesting direct dependencies on
raw action targets.
