feat(tftf): add tests to access invalid memory
Add test framework to access memory addresses which are not accessible
to tftf. The test only introduced for "aarch64" as there is no sync
exception handler for "aarch32".
The test framework will catch the error and do graceful exit.
For now only test introduced is to access memory owned by EL3, which can
be easily extended to add more tests to access realm/secure(in RME
enabled systems).
Platform needs to provide test address, if not then test will
be skipped.
Test steps:
1. Register a custom sync exception handler(try & catch)
2. Access a protected memory, should give data abort.
3. Exception handler should check if data abort then continue.
4. Unregister custom exception handler.
