Add UTF8 support for .properties files (#3358)

Browse source 
Co-authored-by: Josh Roy <10731363+JRoy@users.noreply.github.com>

Based on edaa4f6, this allows messages files to be read in UTF8 without the need for native2ascii conversion. This also removes the native2ascii-maven-plugin, previously used to convert Crowdin translations to a compatible format. I've tested this briefly and it appears to work correctly with both internal translations and custom messages.
