[OnionSoup] Move payment_{app,request}.mojom into blink/public/mojom/

As part of Onion Soup effort, blink/public/mojom/payments/ should be the
right place for payment_{app,request}.mojom, this CL moves them there
from blink/public/platform/modules/payments/.

This movement facilitates moving
//content/common/service_worker/service_worker.mojom into
blink/public/mojom/service_worker/ in future.
