Add integration test for testing the arch variant passed to cc modules included in APEXES.

Resend aosp/2350557, with minor change on line 65 of apex_cc_module_arch_variant_tests.sh.
The pattern was:
  '.*android_target.*: ([0-9]+)$'
and is changed to:
  '.*opt-ST.*: ([0-9]+)$'
since the Bazel output directory name has been changed.
