single line files without newline show findings as global message

```cpp int f(int*p){return *p;} ```  If you add the newline at the end of the line it shows up in the `Problems` tab as expected.

display `unmatchedSuppression` findings

We currently suppress `unmatchedSuppression` findings unconditionally but this is actually something interesting as it will indicate no longer applying (inline) suppressions.

Multiple warnings on same line might not be shown

Implement using ExternalAnnotator

From https://youtrack.jetbrains.com/issue/CPP-22882#focus=Comments-27-5675064.0-0 `LocalInspectionTool` is not designed for running external executables, like `cppcheck`. For such task, `ExternalAnnotator` should be used. The flow is similar: inherit this class, override `collectInformation` to get...

Currently the configured command-line options are global and affect all projects. In case you need to specify a special option this would affect all projects. We should probably move the...
