hgrc: search XDG_CONFIG_HOME on mac
Searching for hgrc was special cased not to look through ~/.config/hg on Mac,
but that’s unnecessary: Macs support it as do other unix based systems. There
are plenty tools that use it there, e.g. git, and people expect it to work, e.g.
"https://stackoverflow.com/questions/72499837/mercurial-on-macos-doesnt-read-config-hg-hgrc".
Initial code introduced in 354020079723.
