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).
