ci(cm): add test_config to validate EL1 ctx with TSP

* This patch adds tfa and tftf build configs and the appropriate
  run_config fragments required to enable the features, which
  are covered until v8.9.

* TSP is the secure world software component and TFTF is the Normal
  world component, which exercises EL1 context registers in this test.

* Build configs ensures most of the EL1 context registers are getting
  involved in the test environment.
