AK: Fix usage of constexpr within Utf16View and related utilities

Browse source 
* Error and ErrorOr are not themelves constexpr, so a function returning
  these types cannot be constexpr.

* The UDL was trying to call Utf16View::validate, which is not constexpr
  itself. The compiler will actually already raise an error if a UTF-16
  literal is invalid, so let's just avoid the call altogether.
