Fix for completion display bug with tmux/IntelliJ

[michaelorr]

IntelliJ terminal requires zle redisplay to be called but this breaks completion menus in non IntelliJ terminals.

This uses an environment variable to detect whether we are in an IntelliJ terminal and only calls zle redisplay for those environments. See also: https://youtrack.jetbrains.com/issue/IDEA-191464/Add-environment-variable-to-terminal-detect-if-running-in-IntelliJ-IDES

Previously the code tried to guard against this bug by looking at $LASTWIDGET but unfortunately we cannot reliably assume that the completion widget has complet in the name (on my personal setup, I saw autosuggest-suggest and self-insert as the $LASTWIDGET during completions depending on context and other zsh plugins enabled).

I do not use IntelliJ and I would love if someone could validate behavior inside the IntelliJ terminal. I have seen reliably that IntelliJ should be setting this environment variable and I can validate that setting this environment variable reintroduces the bug for non-IntelliJ terminals and removing the environment variable fixes the bug for non-IntelliJ terminals

Hey @jeffreytse , no real urgency but I'm just curious what would be necessary to help move this forward?
