  [HLSL] `constexpr` vector element conversions (#195173)

This PR updates the constant expression evaluators to support HLSL's
element-wise vector element conversions. These conversions allow
element-by-element conversion of a vector from one type to another
vector of the same dimension.

Fixes #163437
