AK: Add AKString::split_limit to split strings with a limit

Browse source 
This is a small change to the existing split() functionality to support
the case of splitting a string and stopping at a certain number of
tokens. This is useful for parsing e.g. key/value pairs, where the value
may contain the delimiter you're splitting on.
