  1. releasetools: do not remove dynamic partitions in system-only builds 

    * Before this commit, the generated `dynamic_partitions_op_list` in
  FullOTA packages always tries to remove all partitions and recreate
  them upon flashing. This makes it impossible to have a system-only
  "FullOTA" because vendor partition(s) are always removed.

* This commit detects if a build is vendor-less and disables every
  dynamic partition operation except `resize`, in order to keep the
  original content around after the flash. The change should not affect
  non-dynamic-partition or builds with vendor image included.

  2. Generate block based OTA for product partitions 

    Currently only the system and vendor partitions are updated in the
generic block based OTA generation script. Since the product partition
is quite large and consist most of APK files, it would be beneficial to
update it similar to system. Handle the odm and system_ext partitions in
the same way as well.

Bug: 132683080
Test: Run unit tests, generate full and incremental OTA with product partitions.
