fix(cmakev2/kconfig): do not automatically generate the kconfig_menus.json file

Currently, when the initial sdkconfig is generated, the
kconfig_menus.json format is also created alongside other formats like
CMake, JSON, or C header. The kconfig_menus.json depends on the Kconfig
hierarchy and cannot be generated globally. It must be generated for
each executable to ensure that included and excluded components are
correctly positioned within the Kconfig menu hierarchy. Remove the
automatic generation of kconfig_menus.json.
