AK: Inline *String::is_one_of<Ts...>()

Browse source 
Previously this was generating a crazy number of symbols, and it was
also pretty-damn-slow as it was defined recursively, which made the
compiler incapable of inlining it (due to the many many layers of
recursion before it terminated).
This commit replaces the recursion with a pack expansion and marks it
always-inline.
