Add a Kconfig.env_vars attribute that lists env. variables
Kconfig.env_vars is a set() with the names of all environment variables
referenced in the configuration.
Can be used e.g. for custom incremental build implementations, though
sync_deps() already indirectly catches any relevant changes to
environment variables.
