[upstream_ut] test_zero_dtypes_without_fill_kernel_xpu: fill_xpu not implemented for Bits/Float4

## Description
test_zero_dtypes_without_fill_kernel_xpu_* fail for bits1x8, bits2x4, bits4x2,
bits8, bits16 and float4_e2m1fn_x2. zero_() on a view of these dtypes dispatches
to fill_xpu, which is not implemented for these types.

## Error log
```
File "test/test_torch.py", line 171, in test_zero_dtypes_without_fill_kernel
raw.view(dtype).zero_()
NotImplementedError: "fill_xpu" not implemented for 'Bits16'/'Bits8'/'Bits1x8'/'Bits2x4'/'Bits4x2'/'Float4_e2m1fn_x2'
```

## Reproduce
```
python test/test_torch.py TestTorchDeviceTypeXPU.test_zero_dtypes_without_fill_kernel_xpu_bits16
```

Start by running test/test_torch.py TestTorchDeviceTypeXPU.test_zero_dtypes_without_fill_kernel_xpu_bits16 and review test_zero_dtypes_without_fill_kernel in that file. Trace the zero_() dispatch to fill_xpu for the listed Bits and Float4 dtypes. Done means the XPU test passes for bits1x8, bits2x4, bits4x2, bits8, bits16, and float4_e2m1fn_x2 without the NotImplementedError.
