GN change disallows sources that aren't a source, header, or object file.
We need to pass `process_only` flag to process_version to not create source_set
out of the version file.

Disallow non-buildable sources in binary targets

When adding a file that's not a source, header, or object file to a source_set,
loadable_module, shared_library, executable, or static_library, gn will now
generate an error like the following:

ERROR at //third_party/protobuf/proto_library.gni:369:15: Only source, header,
and object files belong in the sources of a
source_set. //out/Test/pyproto/google_apis/gcm/protocol/mcs_pb2.py is not one of
the valid types.
    sources = get_target_outputs(":$action_name")
              ^---------------------------------
See //google_apis/gcm/BUILD.gn:78:1: whence it was called.
proto_library("proto") {
^-----------------------
See //BUILD.gn:89:7: which caused the file to be included.
      "//google_apis/gcm:gcm_unit_tests",

    Create more Mac Helper application bundles.

    In order to enable the hardened runtime, which restricts things such as
    writable-executable memory and loading code signed by a different Team
    ID, special code signing entitlements must be granted to the Helper.
    To keep the capabilities scoped to the process types that require them,
    this CL adds two new variants of the Helper app: one for renderers
    and one for plugins.

    Currently all three Helpers will be code signed in the same way without
    any entitlements, but this will change in the future.

Notification scheduler: Plumb dependencies to glue class.

This CL plumbs dependencies into scheduler glue class, and starts to
connects several subsystems together.

Tests will be added in following CLs to keep this CL smaller, and
there are still many things not implemented in the glue layer yet.

    Move WebRequest to the UI thread

    Now that network service is launched, there is no reason to have
    WebRequest run on the IO thread. This moves all WebRequest code and
    the WebRequestProxyingURLLoaderFactory to the UI thread, which
    eliminates thread hops. For more info, see the Chrome IO Thread

    Save and restore tab groups

    This implements basic session restore functionality for tab
    groups. Currently, only whole browser session restore is supported;
    restoring a window or a tab from the history menu won't restore
