This PR changes the `queue.fill()` implementation to make use of the native functions for a specific backend. It also unifies that implementation with the one for memset, since it is just an 8-bit subset operation of fill. In the CUDA case, both memset and fill are currently calling `urEnqueueUSMFill` which depending on the size of the filling pattern calls either `cuMemsetD8Async`, `cuMemsetD16Async`, `cuMemsetD32Async` or `commonMemSetLargePattern`. Before this patch memset was using the same thing, just beforehand setting patternSize always to 1 byte which resulted in calling `cuMemsetD8Async`. In other backends, the behaviour is analogous. The fill method was just invoking a `parallel_for` to fill the memory with the pattern which was making this operation quite slow. This PR depends on: - oneapi-src/unified-runtime#1395 - oneapi-src/unified-runtime#1412

There is an issue with
hipMemset2Din ROCm prior to 6.0.0 version and this PR adds a workaround for it incommonMemSetLargePattern.The issue appears only when using a pointer to host pinned memory from
hipHostMalloc. I believe such a case hasn't been used until trying to refactor the USM fill (intel/llvm#12702).Testing intel/llvm: intel/llvm#12898
