natvis visualizers do not follow typedefs

[Trass3r]

See microsoft/vscode-cpptools#3038

The typename retrieved from var-create here could be a typedef.
If the type name can't be matched it should try the actual type retrieved via whatis:

`whatis MyType
<-1539-interpreter-exec console "whatis MyType"
->~"type = std::vector<int, std::allocator<int> >\n"

I guess it could be implemented in https://github.com/microsoft/MIEngine/blob/master/src/MIDebugEngine/Natvis.Impl/Natvis.cs#L929 with something like await _debugger.ConsoleCmdAsync("whatis " + variable.TypeName, allowWhileRunning: true); @pieandcakes ?
Or it could always be resolved during var-create or an additional property added to IVariableInformation.

@WardenGnaw Can you check this for @Trass3r

I think the problem was that whatis only strips 1 typedef level and things get more complicated with pointers/references.
And ptype/mt prints a lot of internal details when structs are involved.

It also seems to strip default template arguments:

+ptype/mt std::unique_ptr<int, std::default_delete<int> >
type = std::unique_ptr<int>

And there is no MI version of these commands: https://sourceware.org/bugzilla/show_bug.cgi?id=8143

Ohhhhh thanks for looking into this!
