Add destination_timeout arg to ios_xctestrun_runner

Adds the ability to override the default `xctest -destination-timeout` value (30 seconds) in the `ios_xctestrun_runner` rule.
If using the rule is not possible, the same can be done with `--test_arg="--command_line_arg=-destination-timeout=VALUE"`.
