[clang-tidy] modernize-loop-convert for pointer and size

[lcsondes]

When working with a C API, I often receive arrays as a separate pointer and size. I'd like this pattern to be supported by modernize-loop-convert:

void foo(int* array, int size)
{
    for(int i = 0; i < size; i++)
        std::cout << array[i];
}

To become something like this:

void foo(int* array, int size)
{
    for(int i : std::span(array, size))
        std::cout << i;
}

This is not a false positive.
