Add source code navigation features for .NET #regions

[vsfeedback]

This issue has been moved from a ticket on Developer Community.

Some code have large "regions" (or embedded regions) and it very hard to know in what region the code you are viewing is.

Adding a "region" navigation menu in the little top bar of the source code editor could be very usefull (like navigation for project/class/members)

I will be easy to know where you are and also easy to navigate quickly to another region of the code.
