This PR is a follow-up to #11769
It implements the following ops for Vulkan:

  • GGML_OP_ROPE_BACK
  • GGML_OP_RMS_NORM_BACK
  • GGML_OP_SILU_BACK
  • GGML_OP_SOFTMAX_BACK

Shaders are mostly copy-pasted from CUDA kernels with inspiration from existing Vulkan shaders for wg sizes.
ROPE_BACK is implemented using the existing RoPE shader (but with negative angle).

The backend tests all pass for me (RTX 4070). I reviewed the code, though I didn't review the shader calculations in great detail.
