RFR: JDK-8311285: report some fontconfig related environment variables in hs_err file

Tue Jul 4 11:55:08 UTC 2023

There are a number of important environment variables influencing how fontconfig works.
See for example
https://man.archlinux.org/man/fonts-conf.5
Some of them should be added to the list of reported environment variables in hs_err file because e.g. a bad setting for some of them can even lead sometimes to crashes.
