Chris Bracken 82fdaae8a6 Use runtime checks for arguments, out directory (flutter/engine#27978)
Since verify_exported.dart is not run with assertions enabled, replace
the assertions with runtime checks and appropriate error messages:

* Adds a check for valid arguments and emits usage otherwise
* Adds a check for the presence of the out/ directory and exits with
  error if it does not exist.
