test(cactus): prevent root region access from swd
This change adds TFTF and cactus test to permit checking a root region
cannot be accessed from secure world.
A hardcoded address marked Root in the GPT is shared to a secure
partition. The SP retrieves the region from the SPM, maps it and
attempts a read access to the region. It is expected to trigger a GPF
data abort on the PE caught by a custom exception handler.
