[JENKINS-54870] Allow for publishing Cppcheck results for FAILED builds

[thomas-dee]

This commit adds two extra parameters to publishCppcheck:

ignoreBuildResult [boolean]

Skip any build result checks and publish Cppcheck results any way.

dontUpdateBuildResult [boolean]

This does not change the current build result based on Cppcheck results. This is useful if you want to handle the build result by yourself.
