In stand-up Peter pointed out that we'll need to localize both "short_name" and "name". I suspect both of these will need some extra re-jiggering to ensure that WebApkInfo/webappregistry gets the localized app name instead of just reading the fields out of the WebApk metadata

The following revision refers to this bug:

Allow localization of WebApk name.

We want to support WebAPK with localized names. In this CL:
1. Removes "name" and "short_name" metadata from shell APK's
AndroidManifest.xml.
   Instead, these two fields in WebApkInfo and the application label will
   obtained from resources (string).
2. Adds non translateable strings.
3. Ensures WebApkInfo is compatible with existing WebAPKs that don't have these
   two strings.
