Add CC analysis support to ide_query

Introduces ide_query_cc_analyzer, which figures out relevant build targets that needs to be built for a given C++ source or header file.
Once these targets are built, it analyzes the sources in question and reports any generated files that are used back.

Full ide_query integration relies on this binary also being available in prebuilts clang-tools, it'll be done in a future patch.
