1) Update WebAppSpecifics proto to be in sync with WebAppProto,
launch_container field and enum added.

2) WebAppProto::app_id was a redundant value in the dictionary.

app_id is a hash of launch url and it can be inferred from launch_url
field. app_id is the client tag and the storage key.

WebAppSyncBridge::GetClientTag and WebAppSyncBridge::GetStorageKey
will be implemented to return GenerateAppIdFromURL(launch_url).
