* Tolerate win line endings on windows module_util load (#37291)
* tolerate windows line endings when loading windows module utils. Helpful for old custom windows modules.
* add test modules to demonstrate win line ending module load behaviour.
* attempt to fix sanity check failures
* pep8 fix
* explict skip of test modules from shebang check (core modules must still have expected unix style line endings)
* switch to rstrip() following core team meeting feedback
(cherry picked from commit ad94d03ba1)
* Added changelog fragment
* Added ignore rules to older sanity tests
* Removed test files due to old shebang not being possible without bigger change
