Add Tooltip system based on Tooltippery

[Banane9]

Based on Psychpsyo/Tooltippery. The only factor for backwards compatibility with old tooltippery content is supporting tooltips on buttons with a Comment component with the Text TooltipperyLabel:.

Basic version of tooltips, huzzah.

The locale strings should be defined in a separate package, so that they can be updated without a whole release of the gamepack.
It may also need extra code for tooltips where more particular details are required to be added, or to properly determine what to show - e.g. Setting session roles only has their index as an argument.

Mods can also add tooltips to their buttons using the LocalActionButtonExtensions.WithTooltip extension methods.

Maybe the tooltips should only show up if you have the dev tool equipped?

Well, they can appear on any kind of button, I just happened to pick some inspector ones to show it.

Also whoops on the other local slot ones lol
