QDoc: Clarify dependency between QDocCommandLineParser and Config

This change removes QDocCommandLineParser's dependency on the Config
class, and moves the responsibility of setting configuration values to
Config. This is done by turning QDocCommandLineParser into a struct,
and making the QCommandLineOptions in it public. In Config, the new
setOptions() method takes a QDocCommandLineParser from which it reads
the values it needs.

This moves QDocCommandLineParser one step closer to being easy to
test.
