Support table constructor/object initializer on created CLR objects

[SmilingCatEntertainment]

C# supports an object initializer syntax on construction like so:
var myObj = new MyClass() {someOptionalProperty="value"};

Likewise Lua standard 16.1 supports this on its native values via OO syntactic sugar:
myLuaObj = MyLuaPrototype:new{someOptionalProperty="value"};

However, MoonSharp does not support this syntactic sugar when creating CLR objects:
myClrObj = MyClass:__new{someOptionalProperty="value"}; --Expected: myClrObj.someOptionalProperty == "value", actual: myClrObj.someOptionalProperty == nil

It would be nice if creation of CLR objects from Lua respected the same initialization/table constructor syntax available to Lua objects. Bonus if the "__new" CLR constructor method name could be changed/aliased to "new" to be consistent with the rest of the Lua world as well.
