Add tests for new IPsec algorithms in IpSecManagerTest

This CL adds CTS tests that:
- Verify IpSecAlgorithm#getSupportedAlgorithms
- Verify new algorithms are supported in device that first
  launched with SDK beyond R
- Verify IpSecTransforms can be built with new algortihms and
  traffic flows

Since there is no hardware that first launched with SDK beyond R
at the time of writing this CL, tests for new algorithms were
manually enabled and verified on the pixel with an updated kernel.
