Tolerate win line endings on module load 2.5 (#38919)

* 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
