env: Migrate CONFIG_ENV_AES to Kconfig and deprecate
The underlying implementation for ENV_AES has security complications and
is not recommended for use. Please see CVE-2017-3225 and CVE-2017-3226
for more details. Mark this as deprecated now and delete this in the
medium term if no one comes forward to re-work the support.
