honor XDG_CONFIG_HOME environment variable on Windows as well

MS Windows users could benefit from honoring XDG_CONFIG_HOME environment variable as well.

Although some people might thought it was not commonly used on MS Windows.

Actually, some well-known softwares honor this environment variable, as far as I known, git honors this environment variable on all platforms including MS Windows. git introduced this feature as earlier as 2015 (git/git@ea19289) .

Many users host their personal dotfiles on a GitHub repository, they just clone their repository to XDG_CONFIG_HOME, if software do not honor this environment variable, users should do more steps.

I have forgotten why leave the libxml2 package not installed. maybe
because libxml2 depends on [email protected], [email protected], [email protected] at the same time. It
may break the environment.
