[CI] Use stylelint in place of csslint (Samsung#1114)

* [CI] Use stylelint in place of csslint

This commit introduces usage of `stylelint` utility instead of
deprecated and unmaintained `csslint`. YAML configuration contains
options to turn errors in existing code into warnings to avoid CI
failure - it's possible to re-enable these restrictions after existing
code re-styling.
