[PATCH v7 0/6] MR3548: windows.applicationmodel: Implement some functions.

[Mohamad Al-Jaf (＠maljaf)]

Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=52665

I'm unsure how to add tests for this given it requires an app to be installed via MSIX to get a package ID in Windows otherwise `IPackageStatics::get_Current()` returns `0x80073d54`.
