Ben Clayton 4d1d143977 tint/utils: More Vector polish 
* Added a class template argument deduction guide (CTAD) to infer the
  `T` and `N` template arguments. This lets you write `Vector{1,2,3}`
  instead of `Vector<int, 3>{1,2,3}`. This is important as a mismatch
  between the number of constructor arguments and the `N` template
  argument can cause silent heap allocations, which we're trying to
  avoid. The `T` deduction uses the same smarts as the return-type
  deduction of `Switch()`, so:
   * `Vector{1, 2.0}` would construct a `Vector<double, 2>`
   * `Vector{i32, u32}` would construct a `Vector<const sem::Type*, 2>`
* Removed the Vector(size_t) and Vector(size_t, const T&) constructors.
  This is a move away from the std::vector style API, but these are
  rarely more efficient than calling Reserve() and Push(), as you remove
  the redundant initialization. The main reason for doing this is to
  remove ambiguity between `Vector{1}` and `Vector(1)`.
* Added support for covariance conversion
  (`Vector<Derived*, N>` -> `Vector<Base*, N>`).
  Only supports pointers to `Castable`, as this can  only safely work
  with single-inheritance.
* Added support for conversion of `Vector<T*, N>` -> `Vector<const T*, N>`.
  This will remove pointless vector copies from the sem package.
