mocking.rst: add sections on comptime and linktime redirection

Give examples of using #ifdef and __weak symbols to add a layer of
indirection to function calls.

Also show how we can combine link/compile-time indirection w/ runtime
indirection to have zero-overhead for normal builds, while still
limiting the scope of the changes.
