[Refactor]Port C++/CX to C++/WinRT (#34198) ## Summary of the Pull Request Removes all C++/CX code, replacing it with C++/WinRT. ## Detailed Description of the Pull Request / Additional comments Removes all C++/CX code. Renames interop namespaces to be better consumed by CsWinRT. Standardizes all projects on net8.0-windows10.0.20348.0, which is a requirement for C++/WinRT usage. FileLocksmithLibInterop brought to stdcpplatest and static analysis errors were corrected. Removed now unneeded string conversion code from FileLocksmithLibInterop. Changed interop KeyboardHook to use a single hook across all instances. Required because on C++/WinRT we don't have the .NET runtime to bind a object instance to a delegate and be able to pass it to a C function pointer argument (still no idea why this worked correctly on C++/CX to be honest). This change actually makes us create less low level keyboard hooks. Changed some code that depended on arrays since WinRT/C++ returns null instead of an empty array through the interface. ## Validation Steps Performed Built and tested runtime. 2024-08-08 15:26:43 +01:00			`namespace PowerToys`

[Build]Clean the WPARAM warning on IDL (#34223) ## Summary of the Pull Request Cleans a build warning about WPARAM when building the idl file. Seems like typedef is not liked too much when compiling for winrt/Cpp. 2024-08-08 18:52:57 +01:00			`UInt64 message;`
