Remove ToolButton in favor of Button 
ToolButton has no redeeming differences with Button;
it's just a Button with the Flat property enabled by default.
Removing it avoids some confusion when creating GUIs.

Existing ToolButtons will be converted to Buttons, but the Flat
property won't be enabled automatically.

This closes https://github.com/godotengine/godot-proposals/issues/1081.
