`Hermitian()` wrapper missing a GPU compatible iterator

The following reproducer code fails with `LoadError: Scalar indexing is disallowed.`:

```
using CUDA
using LinearAlgebra

A = CuArray(ones(Float32, 5, 5))

# This works
any(isnan, Symmetric(A))

# This does not
any(isnan, Hermitian(A))
```

It seems that some underlying function call tries explicit element access with the `Hermitian()` wrapper, but not with `Symmetric()`. I am not 100% sure whether that issue belongs here or in `LinearAlgebra`.

I get this issue with Julia version 1.10.8 (LTS) and 1.11.3 (current stable).
