Remove Vector's non-template span constructor

Reviewed by Sam Weinig.

A std::span can be constructed from a range, so when any compiler is using Microsoft's STL
using C++23 and compiles a file that includes IDBKeyData.h, it causes a confusing compiler
error because the std::variant implementation checks std::is_trivially_move_constructible
on all the types, which tries to instantiate the move constructor of each type, which finds
the std::span constructor of Vector that is not a templatized constructor so it is not a
substitution error, it is a compiler error.  The constructor was only there to help with
constructing Vectors from std::arrays, so instead we just add a template constructor that
takes a std::array and makes a std::span from it.  This covers all the uses except 2 in
CryptoKeyOKPCocoa.cpp where we were trying to make a Vector from a uint8[32] so for those
cases we just explicitly make a std::span and 2 in {Audio,Video}EncoderGStreamer.cpp where we need
to explicitly call the std::span constructor to make an optional vector.

I think this is the second to last blocker to us adopting C++23.
