copy script/static-checks folder from tf-a-ci-scripts

This is a complete copy of the folder [1], based on working dir
from commit [2]. Some checks DO NOT apply to TF-M project, but we
introduce the code as it is from TF-A project for completeness and
then further commits will remove/change relevant tests.
