Add a parser to libtuning for parsing configuration files in yaml
format.

At the moment it doesn't parse anything and simply returns an empty
config. This is fine for the time being, as the only user of it is the
rkisp1 tuning script, which only has an LSC module which doesn't consume
anything from the configuration file. When a module comes around that
requires the yaml parser, it can be implemented then.

Changes in v3:
- add file description
- remove indirection from fake polymorphism
- update commit message to reflect the fact that it doesn't actually do
  anything at the moment
