Migrate remaining preinstalled web apps from Chrome OS JSON to C++

This CL is a follow up to
https://chromium-review.googlesource.com/c/chromium/src/+/2524809/
where the remaining default installed Chrome apps are migrated over to
preinstalled web apps:
 - Gmail
 - Google Docs
 - Google Drive
 - Google Sheets
 - Google Slides
 - YouTube

This copies the JSON configs in
https://chrome-internal.googlesource.com/chromeos/overlays/chromeos-overlay/+/master/chromeos-base/chromeos-default-apps/files/web_apps/docs.json
to C++ in the Chrome binary. The JSON configs will be removed
in a follow up CL to avoid data duplication in multiple
locations and formats.

The icons used by these default apps are stored in an internal
repository: https://chrome-internal.googlesource.com/chrome/components/default_apps/+/refs/heads/main
