AK: Remove StringView(char const*) :^)

Browse source 
This constructor relied on running strlen implicitly on its argument,
thereby potentially causing out-of-bound reads (some of which were
caught a few days ago). The removal of this constructor ensures that the
caller must explicitly pass the size of the string by either:

1) Using operator""sv on literal strings; or
2) Calling strlen explicitly, making it clear that the size of the view
   is being calculated at runtime.
