wifi: Create our version of ArrayUtils

Wifi stack uses only a few simple utility methods from the internal
ArrayUtils class. Internal ArrayUtils class has a bunch of @hide
dependencies, so can't easily jar-jar it. So, create our version of
ArrayUtils with only the methods we currently use. Most of these are
very trivial helper methods, so duplication should be ok.
