DeltaPerformer: add static PreparePartitionsForUpdate

Expose a static PreparePartitionsForUpdate for
implementation of AllocateSpaceForPayload.

- If this function is called multiple times with the same
'update_check_response_hash', calls after the first call
has no effect.

- If this function is called again with a different
'update_check_response_hash', space is re-allocated.

- DeltaPerformer::ResetUpdateProgress deletes the stored hash
and cause the next PreparePartitionsForUpdate to always re-allocate
space.

- DeltaPerformer::ParseManifestPartitions now set error code to
kNotEnoughSpace when appropriate.

Test: apply an OTA manually
