Update build.yml (#3779)

* Update build.yml

Currently we run all actions for all commits. This is not resource friendly. Let's tweak this a bit.

This commit adds support for "skip ci" tags (i.e. if the head commit contains [s k i p   c i] (w/o the extra spaces used to escape here), no jobs are executed.
In addition are all commits which modify non-code files (e.g. README) only excluded.

Furthermore we should not run cppcheck and scan-build if only profiles are changed and sort.py need only to be execute if profiles are changed.

* Create sort.yml

* Update build.yml

profile-sort is now in sort.yml

* Update sort.yml

fix syntax

* Update codeql-analysis.yml
