Add all apexes to apex_info

Previously, META/apex_info.pb contained only /system/apex apexes. Now,
it has all apexes from all possible partitions.

The main purpose of this file is to caculate the decompressed apex size
when applying OTA. Hence it should have all apexes, not just system
apexes.

Test: m dist # check META/apex_info.pb
