[Feature Request] More compile time feature flags

[rlabrecque]

The idea with this is; with other features such as:

• ImPlot
• ImGui Docking branch
• NetImGui
• FontAwesome

It would be really nice to have all of those in a single branch where you could opt in/out of each of them either with a define in your target.cs, or by enabling an additional plugin (like https://github.com/jorgenpt/Hermes does for it's Branch Support), etc.

If something like this is desired I could allocate some time on my team to evaluate this. Would probably focus on getting the ImGui docking branch living next to the regular ImGui and ImPlot, and then figuring out the least painful way to flip between the two without modifying UnrealImGui itself.

That would be beneficial!
