hexagon: activation ops update (#25974)

• hex-geglu: optimized all-in-one geglu microkernel

• hex-geglu: enable non-contiguous src and strided DMA

• hex-act: enable non-contiguous srs and strided DMA for rest of ACT ops

• hex-act: generalize GLU per-thread functions via DEFINE_GLU_PER_THREAD macro

• hexagon: move UNARY_SILU and UNARY_GELU to unary-ops

• hex-act: replace the generic ops_context scratchpad usage with a local htp_vtcm_layout computation per act op.
