UpdateEngineUpdateAttemptReported: add super and slot size, and free space 



Additional information are important to evaluate the impact of Virtual
A/B on devices especially related to OTA take rate.
In order to find a correlation between the OTA take rate and the storage
composition, the following metrics are added to the
UpdateEngineUpdateAttemptReported:
- super_partition_size_bytes: the size of the super partition,
- slot_size_bytes: the size of the current slot, and
- super_free_space_bytes: representing the free space in the super
partition.
