  Use TSpan for TType's array sizes
  
  Until C++20, std::vector doesn't have a constexpr constructor, which
  means TType cannot use a `TVector` for `mArraySizes` if an arrayed type
  needs to be created constexpr.  This is needed for the upcoming
  textureGatherOffsets implementation.
  
  A new TSpan class is introduced, based on std::span (from C++20) that
  holds the pointer/size allocated from a TVector without owning it.
  Since TVector's allocation are made from a pool, the allocated memory
  will live beyond the vector's destruction.  `TType::mArraySizes` is
  changed to this type.
  
  This change will allow a new constexpr constructor to be added to TType
  that takes a TSpan as array directly, a value which is constexpr
  initialized from a static array (instead of TVector).
