tools/memory-model: doc: Describe the requirement of the litmus-tests directory

It's better that we have some "standard" about which test should be put
in the litmus-tests directory because it helps future contributors
understand whether they should work on litmus-tests in kernel or Paul's
GitHub repo. Therefore explain a little bit on what a "representative"
litmus test is.

are listed in litmus-tests/README. A great deal more litmus
tests are available at https://github.com/paulmckrcu/litmus.
By "representative", it means the one in the litmus-tests
directory is:
1) simple, the number of threads should be relatively
small and each thread function should be relatively
simple.
2) orthogonal, there should be no two litmus tests
describing the same aspect of the memory model.
3) textbook, developers can easily copy-paste-modify
the litmus tests to use the patterns on their own
code.
