[ios] Flag ownership ewannpv gambard olivierrobin sczs thegreenfrog

We're bringing Chrome Flag Ownership to iOS
go/chrome-flags-ios

More about flag ownership here:
https://chromium.googlesource.com/chromium/src/+/master/docs/flag_ownership.md

This CL adds flags used in iOS with these owners:
ewannpv@
gambard@
olivierrobin@
sczs@
thegreenfrog@

Note that the unit test to enforce flag ownership in iOS is not
yet enabled. It will be enabled once all iOS flags have
been added to flag-metadata.json.
