Subject: Implement updater runtime for dynamic partitions

The simulator skips executing the operations for dynamic partitions, and
will use the logical images under target_files/IMAGES directly. (Similar
to the targets without DAP enabled)

Bug: 131911365
Test: run update on cuttlefish, run simulator
