Chat Copy Button Visibility Toggle
The goal of these changes is to allow for players to hide the chat copy button (toggle?) within the chat frames in elvui. This option is exposed as a toggle-able setting in elvui options.
Easily using Details Damage Meter's chat frame embed function without needing to use the AddonOnSkins and getting annoyed by the presence of floating icons in the chat channels. There's also a few Reddit threads of users attempting to accomplish this.
This is my first time contributing to a WoW Addon so I'm not sure what the typical unit or integration testing story is here. I'm also not sure if the organization has any coding standards for Lua or the package but I will be happy to update to conform with those if I need to. I did validation locally of as many cases as I could think up and everything looks good. Please see the attached video of local testing.
