Support 2.0 CppWinRT

[licanhua]

To support this, we migrate/author instance_rt/reactControl_rt/ module_rt in a new way. Here are some details we need to pay attention to:

• Update CppWinRT nuget from 1.0 to 2.0
• Remove all term of ABI
• Remove all Microsoft::WRL::ComPtr and replace then with winrt:: namespace.
• vcxproj change and target changes. for example, remove midlrt.targets
• It's possible that we don't need mdmerge target
• Remove OLD_CPPWINRT
• Check with other workstream who use make.inc

This would be nice to do but not high in priority. marking as nice-to-have.

The left task is to move WRL to cppwinrt.
Since IModule and other WRL implementation would be moved to other project, I will close this task, and left task is tracking by #3236
