This makes it possible to do a fresh clone of this repo in Windows, and
be able to run the resetdeps command successfully and then have a clean
git status. We now check for a clean git status in during CI in Windows
which was previously excluded.

The changes required were to:
- Delete our workspace symlinks from node_modules and add a step to
  resetdeps that will do a platform dependent symlink before the initial
  reification
- Add line ending normalization to our `.gitattributes` file and commit
  the result. Git will store text with LF line endings automatically,
  except for some files like `cmd` scripts that need to be `crlf` and
  shell scripts that need to be `lf`.
- Update workflows to call `node scripts/resetdeps.js` directly since a
  fresh clone of the repo wont have any symlinks in place, so any
  `node .` command will fail due to missing workspaces.

* add ps1 scripts

Resolves UNC path issues because powershell.exe
supports UNC, while cmd.exe doesn't.
(Which is why npm.cmd doesn't work within
UNC paths, even under powershell)

Resolves #6280

* fixup: add tests and prefix for ps1 scripts
