Revert^2 "Add disable/get/set_hidden_api_enforcement_policy extensions"

This reverts commit 46d6fc0e16d65468aa259fadf27ddfeef72987b7.

The test, 2038, is incompatible with redefine stress due to class
redefinition disabling most hidden-api checks. This adds the
appropriate skips to knownfailures.json.

Reason for revert: Add 2038 to redefine-stress knownfailures.json
Test: ./test.py --host --redefine-host
Bug: 175329755
