Make it possible to view the raw output

[firewave]

Currently there is no way to look at the Cppcheck output from inside the IDE. You need to call it manually with the proper command-line options you get that.

We should provide an action which will show the whole raw output of the analysis for the current file similar to the Show Clang-Tidy Info action within CLion.

We should also make the --debug output available so it is easier to file upstream bug reports.
