Handle resume of VABC updates by emitting labels
To support resuming an update with Virtual AB Compression, we emit
labels in between operations. After writing all SOURCE_COPY, we
emit label 0. Each time we finished writing an InstallOp, we emit
a label incremented by 1. When resuming, we pass the label to CowWriter.
Test: treehugger
1. update_device.py ota.zip
--extra-headers="SWITCH_SLOT_ON_REBOOT=0"
2. update_device.py ota.zip
3. Verify that 2 did not re-start the entire update,
only fs verification and postinstall may re-run.
