storageproxyd: Integrate new command arguments

Background:
* Adds argument to explicitly define storage backings for secure
  storage files.  Storageproxy will also internally manage the creation
  of symlinks as necessary (Useful for determining if a userdata wipe
  has occurred).
* Adds an argument to define the max size for file backed storages.

Bug: 324989972
Test: Storage port tests running
