Plugin description tooltip has no limits

Windows 10.0.19045 - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1060 (NVIDIA; 30.0.15.1403) - Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz (8 Threads)

Issue description

This is a plugin description that spans 2 screens and goes beyond the right screen border.
I just wanted to test if there is any limit to plugin description size. There is none. You can potentially put a text that will cover your whole screen (don't try it 🙃).

Not sure how we should solve that. We could autowrap the label, but to gracefully display extremely long texts they either need to be scrolled (in a tooltip??) or truncated.

Steps to reproduce

1. Open Project Settings
2. Go to Plugins -> Create New Plugin
3. Write a book in the Description field

I suggest using String's wrap function to wrap lines in the tooltip to 80 characters or so (using a per-word basis).

We should do the same for project description tooltips in the Project Manager, and editor description tooltips in the Scene tree dock.

We actually have a function for that, here's example usage:

godot/editor/gui/scene_tree_editor.cpp

Line 138 in d28f9af

const PackedInt32Array boundaries = TS->string_get_word_breaks(config_err, "", 80);
