hexagon: add HTP kernel for GGML_OP_GATED_DELTA_NET (#22837)

Implement the Gated Delta Net recurrence on HVX with:

• 4-row fused kernels for PP (prompt processing) path
• 8-row fused kernels for TG (token generation) path, reducing
  K/Q/gate vector reload overhead by 2x
• Separate PP/TG thread functions for I-cache isolation
• VTCM state scratchpad with DMA in/out for TG single-cycle access
• Vectorized gate exp via hvx_exp_f32
