From: David Hu <david.hu2@arm.com>

TF-M build system has introduced a ground-breaking change since v2.0.0.
Enable TF-M regression test build, following build instructions in TF-M
document [1].

Add the BUILD_REGRESSION_TESTS variable to enable regression test
builds. Individual regression test suites can be selected by
passing the appropriate TF-M CMake options through EXTRA_OECMAKE.
If regression test is enabled, build TF-M and tests from tf-m-tests
directory.

The build files for Normal World build will be installed.
