Invalid strides type for static extents of rank one

[amitsingh19975]

Right now, the static tensor gets confused about which strides type it should use for rank one extents because of the ambiguity between the extents_static_rank<4> and extents_static<4>. This ambiguity occurs because, behind the scene, they both are the specialization of the extents_core<...>.

When we create a static tensor of rank one, instead of choosing the strides from the extents_static, it chooses the strides from the extents_static_rank.

auto t = tensor_static<float, extents<2>>(); // error: no viable conversion from 'const array<[...], 1>' to 'const array<[...], 2UL aka 2>'
