ClangToolRunner: Add done(const AnalyzeOutputData &) signal

Introduce AnalyzerOutputData structure that is passed inside
new done() signal. This signal replaces the finishedWithSuccess()
and finishedWithFailure() signals. The output structure contains
all the data required in clients' handlers.

Move AnalyzeUnit into clangtoolrunner.h in order to avoid
circular dependencies.

Get rid of outputFilePath(), as it's passed inside AnalyzeOutputData
now.

Inline ClangToolRunWorker::unitsToAnalyze() as it's used only once.
