ggml : fix interpolate with align-corners and ne=1 (#16700)

Browse Source 
* ggml : fix interpolate with align-corners and ne=1

* avoid division by zero if one of the spatial dimensions is 1
* cpu, cuda, opencl returned correct result anyway due to clamp
* vulkan didn't clamp for align-corners so results were broken

* fix clang warning
