`apple_resource_bundle` should bundle a default Info.plist if `infoplists` isn't set

A resource bundle without a valid Info.plist won't work correctly (e.g. no images will be found in it). Since `infoplists` is optional, it's easy to create a resource bundle that doesn't work, and is really hard to debug what is wrong.

No source files or tests are named in the issue. Start by locating the apple_resource_bundle rule and the handling of the optional infoplists attribute, then inspect how resource bundles are tested. Done means a bundle without infoplists contains a valid default Info.plist and works correctly for resource lookup.
