I found the reason why the bot failed.

GN's create_bundle target sometimes does not make direct dependency to its deps/public_deps targets.
But recursive hard deps keeps such dependency from indirect relation until my change is landed.

In the issue 'Google Chrome Framework.framework/Google Chrome Framework' is generated in 'chrome_framework_package' and create_bandle('chrome_framework') has dependency to 'chrome_framework_package'.
https://chromium.googlesource.com/chromium/src/+/43fcb5eb66460fb63755f3a9383e4a6131afcc82/chrome/BUILD.gn#1226

But such dependency is not generated by directly from GN.
We need to consider deps/public_deps in
https://chromium.googlesource.com/chromium/src/+/43fcb5eb66460fb63755f3a9383e4a6131afcc82/tools/gn/ninja_create_bundle_target_writer.cc#54

I'll add such dependency in create_bundle target.

GN: Handle deps always in create_bundle target

Stop to use explicit dependency for indirect dependency in the CL broke
Mac builder.
https://chromium-review.googlesource.com/1041506

This CL uses deps/public_deps in create_bundle target always not to
miss the dependency.

Original change's description:
> GN: do not make indirect dependency to direct dependency
>
> If a target is hard dep, there is no need to have the action targets's
> recursive deps as direct dependency, because such dependency is
> transitive.
>
> This is found by pcc in gn-dev

> With this change, generated android's toolchain.ninja size is reduced
> from 262MB to 31MB. And ninja's startup time reduced from 4.9~5.1s to

> I used args.gn same with android_n5x_swarming_rel bot.
>
> Also this patch reduced the time of `gn gen` from 9.5~10.3s to 6.8~7.2s
