Add support for Fabric access wideners

[Earthcomputer]

Since Fabric now supports access wideners, it would be very helpful to add a few features

• Highlight access widener files and allow for jumping to the reference
• Detect unused access widener entries
• Error if a method is made accessible but not extendable, but it is being extended
• Warn in the fabric.mod.json if the access widener is not linked (already implemented by the initial Fabric support PR)
• Add a ribbon/balloon to reload Gradle when the access widener changes

Depends on #733

Add a ribbon/balloon to reload Gradle when the access widener changes

That's a neat idea, would be nice to have for forge ATs too.

Bumping this because this would be very useful for us and this hasn't been looked at in a while.

Bumping isn't going to make it go faster, there's a reason I haven't been able to work on this plugin lately. Will get round to it.

Alright, just figured it might have been forgotten over time. No rush 😅

It's useful to support AW/AT and suppress the errors in IDEA

To be honest I don't know why there is still no AW/AT error highlighting, it's unbelievably hard to update these when changing the game's version especially after many versions

[Earthcomputer]

There is a validateAccessWidener gradle task (which gets called automatically by a number of other tasks), which you can use to easily tell you which ones are invalid.

What I do at the moment is hold ctrl and hover all the AW and if I can't click on it then it's invalid, that means that there is already logic for AW/AT and adding error highlighting should be easy no ?
