env: ubi: add support to create environment volume if it does not exist

When U-Boot is booting from a fresh device, the environment volume may not
exist in the factory UBI image. This is a common case where factory UBI
image contains only volumes with valid data.

With the current design, even if the volume is created manually, the
environment will still be unusable (e.g., saveenv) before a reboot.

This patch adds support to automatically create missing volumes before
loading environment. This will make environment available at first boot.

There are two options:
CONFIG_ENV_UBI_VOLUME_CREATE: whether to enable volume creation
CONFIG_ENV_UBI_VOLUME_STATIC: create static volume (default is dynamic)
