AK: Remove ByteString from GenericLexer

Browse source 
A bunch of users used consume_specific with a constant ByteString
literal, which can be replaced by an allocation-free StringView literal.

The generic consume_while overload gains a requires clause so that
consume_specific("abc") causes a more understandable and actionable
error.
