JetBrains: Make resize padding macOS-only and remove bottom padding

Merged Warren Gifford requested to merge ps/jetbrains-resize-paddings into main 2 years ago

Unfortunlaty this is the best I could do. Here are a few observations:

On Windows and Linux, the padding is not necessarily needed. Without it, there are a few fewer pixels that show the resize cursor but I still found it usable. In addition, I was not able to reproduce the issue where resizing would suddenly "stop" on those platforms. Hence I think it makes sense to not show these paddings on that platforms.
On macOS, the left and right paddings are still necessary. Without it, the resizing would stop during the interaction. I also tried to play around with adding custom event listeners (the same way that the StatusText component does internally that is used by the JBPanelWithEmptyText component but I was not able to make it work no matter what I tried :( I did notice, however, that the bottom padding does not seem to be necessary anymore.
