feat: Add functionality to opt out plugin from airgap instance (#22098)

## Description

As a part of supporting airgap instances we want to restrict the plugins
which have any public dependency. This PR introduces a config setting
for plugins to opt out of airgap.
Also as a part of this exercise we are also adding a setting for CS
dependency which can be utilised in future if our customers wants to opt
out of CS dependent plugins.
Corresponding EE PR:
https://github.com/appsmithorg/appsmith-ee/pull/1258

> TL;DR: Provide a way for plugins supported in Appsmith to opt-out of
airgap instances
