fileOutput.param: Sort file and add Hints

This pull request:
- Adds a small comment on how to disable particle output
- formats the file to be sorted by priority and useful groups
- removes all auxiliary defines of `bmpl` to let the user focus on the options that he is actually allowed to set

**Misc:**

Added a note in the [wiki](https://github.com/ComputationalRadiationPhysics/picongpu/wiki/Plugin%3A-HDF5) that `fileOutput.param` controls HDF5.

Adios is controlled by the same file I guess?
- [x] update [adios page](https://github.com/ComputationalRadiationPhysics/picongpu/wiki/Plugin%3A-ADIOS), too
