Prevent "m_" for script class exported member variables from showing in editor

[Vaani-del]

Hi, in my scripts I use "m_" for my member variables (I use C#, not sure how this affects other languages). When I have a variable declared with "[Export]", it appears in the editor like the top variable on the attached image. It would be cleaner (and nicer) if there was an option to ignore the "m_".

Unity's [SerializeField] variables for example, will show it as the second variable in the attached screenshot, and it looks so much better as a result.

I'm not sure if removing one-letter prefixes with no way to opt out is a good idea. Instead, we may want to add an annotation to specify an arbitrary property name to expose: #3510
