Update structure of TypeScript benchmarks

[cmnrd]

With #22, we can run the Philosophers benchmark via the runner python script. However, there are a few more things needed to fully support the runner script and also to have a structure similar to other targets. Here is a list of action items that should be resolved:

• [x] Replicate the file structure used in the other targets. All Savina benchmarks should live TS/Savina/src and be organized in subdirectories micro, cocurrency and parallelism.
• [x] Each benchmark should utilize the BenchmarkRunner reactor to control the benchmark execution and perform time measurement
• [x] Each benchmark should have a lf-ts section in the corresponding yaml configuration file in runner/conf/benchmark/. See conf/benchmark/savina_concurrency_philosopher.yaml for a working example.
• [x] In order to be parameterizable, each benchmark should use the cog code generator to be able to automatically modify the lf proragms and adjust parameters. See the C benchmakrs for examples of how this works. (This only applies if the TypeScript target does not support runtime parameterization)

Let me know if there are any questions.

Closing this because it looks like everything on the list is done.
