informative.fish: stop caching_set_color, use br* directly No longer uses global vars to cache set_color output, this was from before set_color was a builtin, it is pointless now. This is also a prompt from before we had bright named colors, and it appears it was relying on -o red to get bright red. so use brred, etc.

Make prompts forward compatible with fish 3.1.2 by passing locally exported variable Commit 5d135d555 (prompts: fix pipestatus for jobs prefixed with "not") introduced a backwards compatibility hack about adding an optional argument to __fish_print_pipestatus. This hack would break downgrading to fish 3.1.2 if the user copied the new prompt to their config - they would get a backtrace on every prompt which is arguably worse than the patch's minor improvement. This does away with the error trace - old fish just won't show the fancy new pipestatus on `not true`. Implemented by passing the last $status as the poor man's kwarg, which works since 3.1.0 (9b86d5dd1 Export all local exported variables in a new scope). The prompts don't work with fish 3.0.0 or older; downgrading does not seem too important in general but I think this patch is an okay simplification.

Add a function to check if the user is root. Add a helper function to check if the user is root. This function can be useful for the prompts for example. Modify the prompts made root checked to use the function instead. Add also the support of Administrator like a root user. Fixes: #7031

Fix Alt+L when using the "Informative" prompt I ran into problems described in https://github.com/fish-shell/fish-shell/issues/718 when using this prompt. This seems to be a bug in the prompt -- this change fixes it, at least on my system. I tried this in tmux (TERM=screen) and gnome-terminal (TERM=xterm-256) with fish 3.1.2, on Linux.

Add support for toor account. Currently fish doesn't recognize toor as special. However, it's likely that on BSD systems, fish shell will be used on toor, not on root (toor is an intentionally existing account to use more advanced shell on, like shell).
