add an option to disable aliases

[Ryooooooga]

Description

Add an option to disable aliases such as zi and zplg.

Motivation and Context

There is a motivation to minimize unnecessary settings.

Especially since zinit has been renamed from zplugin for three years now, zplg is unnecessary for almost everyone.

Usage examples

# .zshrc

How Has This Been Tested?

Rewrote ${ZINIT[HOME_DIR]}/bin/zinit.zsh and added ZINIT[NO_ALIASES]=1 before source.
