Windows: Non config changes to support Gitlab CI (#43965)

* Quote python for shlex

* Remove python path quoting patch

* spack env: Allow `C` "protocol" for config_path

When running spack on windows, a path beginning with `C://...` is a valid path.

* Remove makefile from ci rebuild

* GPG use llnl.util.filesystem.getuid

* Cleanup process_command

* Remove unused lines

* Fix tyop in encode_path

* Double quote arguments

* Cleanup process_command

* Pass cdash args with =

* Escape parens in CMD script

* escape parens doesn't only apply to paths

* Install deps

* sfn prefix

* use sfn with libxml2

* Add hash to dep install

* WIP

* REview

* Changes missed in prior review commit

* Style

* Ensure we handle Windows paths with config scopes

* clarify docstring

* No more MAKE_COMMAND

* syntax cleanup

* Actually correct is_path_url

* Correct call

* raise on other errors

* url2path behaves differently on unix

* Ensure proper quoting

* actually prepend slash in slash_hash
