vulkan: fix buffer_reference alignment in im2col shaders (#28996) Both im2col.comp and im2col_3d.comp declare D_ptr without an explicit buffer_reference_align, so glslang emits writes through it as Aligned 16. The shaders advance the pointer by D_SIZE, a per-variant define set to 4 for float and 2 for float16_t, so most write addresses are not 16-byte aligned. This triggers VUID-RuntimeSpirv-PhysicalStorageBuffer64-06315 under GPU-AV. Declaring buffer_reference_align = D_SIZE matches the alignment to the actual write stride and takes validation hits from 20 to 0 for both IM2COL and IM2COL_3D.
