Add an int8 (asym8s) accelerated path using xa_nn_vec_leaky_relu_asym8s_asym8s for HIFI3/HIFI4/HIFI5/HIFI_IQ targets, mirroring the existing int16 optimized path. Falls back to the reference QuantizeLeakyRelu on other targets.
Add int8 (xa_nn_pad_8_8) and int32 (xa_nn_pad_32_32) accelerated Pad paths for HIFI targets, complementing the existing int16 path. Inputs with more than 4 dimensions fall back to reference_ops. The int32 path is gated on HIFI3/HIFI4/HIFI5.
Extend existing HIFI kernel guards to include HIFI_IQ so the optimized SVDF paths are compiled for the HIFI_IQ target. No functional change on other targets.
