Add tests for Tunnel, Transport mode application with released SPIs

This change adds tests to validate that both transport and tunnel mode
transforms continue to work even after the SPI resource has been
released. Specifically, since SPI resources are effectively subsumed by
the creation of a Transform, the SPI resource is still "alive", but
removed from the user-tracking sparse arrays.

Bug: 142072071
Test: Added these new tests. Failing prior to aosp/1133555, passes with.
