drivers: wifi: nxp: add CONFIG_NXP_WIFI_BUILD_ONLY_MODE for CI testing

Add CONFIG_NXP_WIFI_BUILD_ONLY_MODE, which allows the NXP WiFi driver to
be built without a binary blob. The built application will not be
functional, but this enables continuous integration to run upstream.

Update NXP HAL manifest to include changes needed to WiFi driver for
this support.
