Use XDG base directories and Known Folders on Windows (#1809)

This changes logic that previously read/wrote from `~/.pkl` to use
XDG base directories (all OSes), and Known Folders locations on Windows.

For example, Pkl will look for `settings.pkl` in:

1. `$XDG_CONFIG_HOME/pkl/settings.pkl`
2. `%APPDATA/pkl/settings.pkl`
3. `~/.pkl/settings.pkl`
4. Path pkl/settings/pkl within `$XDG_CONFIG_DIRS`
5. `/etc/xdg/pkl/settings.pkl`

When Pkl prints source locations, it also prints clickable links for easy access.
For local files, it generates a link for your development environment (https://pkl-lang.org/main/current/pkl-cli/index.html#settings-file[configurable in `+~/.pkl/settings.pkl+`]).

For packages imported from elsewhere, if available, Pkl produces `https://` links to their repository.
Pkl complains about a _type constraint_.
