Built-in vector types float2, float3 and float4 are not trivially copyable

`float2`, `float3` and `float4` are trivially copyable in CUDA, but they are not in HIP.

This results in the following piece of code working in CUDA, but failing in HIP:

```
static_assert(std::is_trivially_copyable_v<float2>);
```

It transitively applies to any class that uses such a data member as well.
