tests: Add build subsystem for unit testing coreboot
Add a subsystem which will be used for writing, building and running unit tests for different coreboot's modules. This work is built using Cmocka unit testing framework. Description of what unit testing means (for the author) and how unit testing framework evaluation was performed may be found in Documentation/technotes/2020-03-unit-testing-coreboot.md Makefiles structure is very similar to this used for building coreboot images. Every directory has its own Makefile.inc were tests' names, sources, subdirs and multiple other test-related attributes are defined in form of variables.
