Support c#9 new() target-typed syntax

[angularsen]

This doesn't trigger the analyzer:

// AssignAll enable
Foo r = new()
{
    Id = ,
    AddedDate = ,
    ModifiedDate = 
};
// AssignAll disable

But this does:

// AssignAll enable
Foo r = new Foo
{
    Id = ,
    AddedDate = ,
    ModifiedDate = 
};
// AssignAll disable
