Replace makefiles with CMakeLists.txt. This will allow for IDE and
platform agnostic builds of FFF.
Update the CI for FFF to use github workflows which don't depend on MS VC.
The workflow added will verify the pull requests sent to master buy
running 'buildandtest' which mirrors the developer workflow.

Using a function that sets a value on a variable via a char pointer, we
test the following:
1 - Does the custom fakes are called in the expected order?
2 - When the sequence length is exhausted, do we only call the last
custom fake in the sequence from then on?
