Q(Any|Utf8)StringView: move array size deduction feature to fromArray

The constructor taking an array literal will now stop at the first
null-terminator encountered.

And fromArray is introduced which only supports array literals.
Constructs a view of the full size. Explicit so it shouldn't be
surprising.
