MLK-22279-2 env: Add a config to enable nowhere as default location
When booting from USB there is no place to store the environment and
should use default env. However CONFIG_ENV_IS_NOWHERE has dependence
with other env storage config. If we enable multiple storages, NOWHERE
can't be enabled. And saveenv won't be built if NOWHERE is set.
This patch introduces a new CONFIG_ENV_DEFAULT_NOWHERE, that can enable
NOWHERE as a default env location when other storage are not avaliable.
And allow to build saveenv.
