Group algorithms do not support marray arguments

### Describe the bug

[Section 4.17.3](https://registry.khronos.org/SYCL/specs/sycl-2020/html/sycl-2020.html#sec:algorithms) of SYCL 2020 says:

> All algorithms are supported for the fundamental scalar types supported by SYCL (see [Table 179](https://registry.khronos.org/SYCL/specs/sycl-2020/html/sycl-2020.html#table.types.fundamental)) and instances of the SYCL `vec` and `marray` classes.

...but DPC++ does not support the `marray` variants.

### To reproduce

```c++
#include

int foo(sycl::queue q) {
q.parallel_for(sycl::nd_range<1>(1, 1), [=](sycl::nd_item<1> it) {
sycl::marray block;
sycl::reduce_over_group(it.get_sub_group(), block, sycl::maximum<>());
});
}
```

Compilation gives the following error:
```

```

`marray` does not satisfy `is_vector_arithmetic` and there is no alternative `is_marray` check.

### Environment

- OS: Linux
- Target device and vendor: Any
- DPC++ version: Intel oneAPI DPC++/C++ Compiler 2024.2.0
- Dependencies version: N/A

### Additional context

There doesn't appear to be a corresponding test for group algorithms with `marray` arguments in the SYCL-CTS.
