Update tests to run in postsubmit

* After searching through go/ath, it looks like none of the hwasan-
postsubmit tests are actually running anywhere. Changing hwasan-
postsubmit to postsubmit in the TEST_MAPPING to ensure our tests run on
postsubmit  at least in the testconfig:
v2/android-virtual-infra/test_mapping/postsubmit-avd.
* Currently CtsInputHostTestCases are not run anywhere. Adding it to to run in post-submit.
After it meets the SLO in postsubmit on all configured targets,
we can consider moving it to presubmit.
