LinAlg: restrict input vector component based on input ComponentEnum

[tex3d]

Description
See the Convert() API in the linalg.h header here:

DirectXShaderCompiler/tools/clang/lib/Headers/hlsl/dx/linalg.h

Line 238 in c763461

Convert(vector<T, N> Vec) {

And the MakeInterpretedVector() API:

DirectXShaderCompiler/tools/clang/lib/Headers/hlsl/dx/linalg.h

Line 230 in c763461

InterpretedVector<T, N, DT> MakeInterpretedVector(vector<T, N> Vec) {

These both need to implement a restriction for the allowed input vector's native HLSL component type based on the ComponentType (or ComponentEnum) enum value for that input vector.

For instance, this check would report an error when using an input vector<float, ...> with ComponentType::PackedS8x32 for that input.

We should also look for any other APIs where this restriction should apply.
