[ci] Simplify windows ci with native opam (#11879)

* [ci] Remove windows 32 ocaml install script

* [ci] Remove installation of perl libraries

These were only needed for camlp5 which has now been removed

* [ci] Remove unneeded PATH step on windows

This is handled now by the mingw-w64-shims package:
https://github.com/dra27/mingw-w64-shims/blob/3c4a82700d9b03443ad6f2927449f7a8f25a77cf/mingw-w64-shims.opam#L8

* [ci] Use cygwin tar

* [ci] Update setup-ocaml

* [ci] Update to latest ocaml 4 release on windows

4.08.1 was not supported natively on windows

* [ci] Add required PATH entries for installing luv

See: https://github.com/aantron/luv/issues/162

* [ci] Run windows make commands natively

With native opam, we no longer need to build from the cygwin bash.

This means we can rely on native git.
