  -----------
  [analyzer] On-demand parsing capability for CTU

Summary:
Add an option to enable on-demand parsing of needed ASTs during CTU analysis.
Two options are introduced. CTUOnDemandParsing enables the feature, and
CTUOnDemandParsingDatabase specifies the path to a compilation database, which
has all the necessary information to generate the ASTs.
