release_config: implement disallow_lunch_use

When set, the release config cannot be directly used for for builds (it
can only be inherited).
- Do not list it in ALL_RELEASE_CONFIGS_FOR_PRODUCT
- When writing the makefile, set _disallow_lunch_use = true, so that
  release_config.mk can generate an actionable error.
