apex: pass partition_tag to host_apex_verifier

host_apex_verifier can check partition-specific checks. For example,
.rc files in APEX don't support 'on' if the APEX is from /system.
To support this, pass the partition tag to host_apex_verifier.

Bug: 223896570
Test: m
Test: host_apex_verifier --apex=<path> --partition_tag=system
   # fails when the apex has .rc file with 'on' section.
