Enable ActivitySecurity__asm_restrictions_enabled for CTS

CTS should work as expected even if the new ams restrictions flag is
enabled, current tests cover some of these restrictions already by
ensuring that caller app can start activites while the sandbox activity
is on top, and upcoming cls will cover other cases like using clearTop
flag.
