Generate hashtree for com.android.appsearch apex

Although the APEX is always shipped in the system image, which already
has dm-verity protected, we need to access to APEX from outside of
Android in a Protected VM.  The VM, which doesn't trust Android, needs
to mount the APEX image and use dm-verity to verify the content.

Bug: 200210074
Test: Boot VM, see the APEX mounted
