Rename microkernel-related types and structures

Use consistent naming for internal structures and related functions
- xnn_qs8_gemm_params -> xnn_qs8_conv_minmax_params
- xnn_qu8_gemm_params -> xnn_qu8_conv_minmax_params
- xnn_qs8_gemm_ukernel_function -> xnn_qs8_gemm_minmax_ukernel_function
- xnn_qu8_gemm_ukernel_function -> xnn_qu8_gemm_minmax_ukernel_function
- xnn_qs8_igemm_ukernel_function -> xnn_qs8_igemm_minmax_ukernel_function
- xnn_qu8_igemm_ukernel_function -> xnn_qu8_igemm_minmax_ukernel_function
