fastfetch: additional feature flags; fastfetchMinimal: init at 2.42.0 (#403209)

Cross checking https://github.com/fastfetch-cli/fastfetch/wiki/Dependencies and https://github.com/fastfetch-cli/fastfetch/blob/dev/CMakeLists.txt to allow more granular control over the features available for a fastfetch build. Also adding a package alias for feature flags disabled to get a smaller closure for those who don't need a full fat install.
