Update ActivityManagerTestBase to use allowlist for task cleanup.

This CL updates ActivityManagerTestBase to use an allowlist approach for
determining which tests should retain the legacy behavior of removing
all tasks except the home launcher during setUp and tearDown. The
allowlist, KeepLegacyTaskCleanupAllowlist, currently includes all
existing ActivityManagerTestBase tests to avoid breaking any CTS tests.

Subsequent CLs will progressively remove tests from this allowlist as
they are confirmed to not rely on the legacy behavior or are updated to
use the force stop cleanup mechanisms.
