Implement InlineVector and use it for lens and strides in TensorDescriptor

[CAHEK7]

During some host-side perf measurements in #3346 we've found out that keeping 2 dynamic vectors for an array of 5 elements is inefficient, since we are extensively creating and coping TensorDescriptor across the library.

To minimize host side overhead we need a simple vector-like container with statically allocate storage of "at most" 5 elements.

It has to be something like template <typename Type, size_t Capacity> class InlineVector;
