modules: hal_nxp: mcux-sdk-ng: Fix LPC55S16 build error

Fix build error when CONFIG_MCUX_COMPONENT_driver.fro_calib is set.
Error message:

modules/hal/nxp/mcux/mcux-sdk-ng/cmake/extension/function.cmake:2084 (if)
  if given arguments:

    "IN_LIST" "NEED_WRAP_TOOLCHAINS"

The error is because, mcux sdk ng cmake functions `mcux_add_xxx` support
add content based on toolchains. CMake should set current toolchain in
CMake Variable `CONFIG_TOOLCHAIN` to use this feature.
