VS Code extension: Add support for Function Breakpoints

[dougbu]

The VS Code "function breakpoints" feature does not seem to work when using the OmniSharp-based C# extension (v1.0.5-rc2). Or, if the feature works, the obvious syntax doesn't. This might be a fine feature gap except the failure is silent -- no warning is shown that the enabled breakpoint is invalid. For example none of the Main breakpoints are hit with the setup below. Same thing goes for non-static methods.

I opened #296 to track the lack of warning. We can use this to track the feature request for function breakpoint support.

Any updates on this functionality? I'm curious and might try my hand at it. How difficult would it be to implement this functionality as a first time contributor?

@loligans [Sorry for the delay, I am returning from parental leave] the debug adapter used by this extension isn't open source, and this feature can't really be implemented outside of it. So this can only be implemented by a Microsoft engineer.

I just ran into this issue. Super annoying if I want to break on a function that isn't my own as well like you can in WinDbg.
