[SYCL][Bindless Image] __nvvm_tex_3d_v4f16_f32 function is probably not tested

[wenju-he]

Describe the bug

#21586 fixes warnings in libspirv and exposed an issue in file libclc/libspirv/lib/ptx-nvidiacl/images/image.cl:

@@ -2576,7 +2582,7 @@ __nvvm_tex_2d_v4f16_f32(unsigned long imageHandle, float x, float y) {

 __attribute__((always_inline)) half4

-  float4 a = __nvvm_tex_1d_v4f32_f32(imageHandle, x);
+  float4 a = __nvvm_tex_3d_v4f32_f32(imageHandle, x, y, z);
   return cast_float4_to_half4(a);
 }

It looks like function __nvvm_tex_3d_v4f16_f32 wasn't correctly implemented before. Not sure if this is covered by another issue or the function is not tested at all.
File this issue to address the test coverage of this function.
