## 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.
* basic logic working
* Added a literal for ignore flag which cna be shared by all the files
* Added a condition that the other modifier keys should not be pressed
* Added comments to describe each scenario
* sometimes when multiple modified keys were involved the shift+tab key press was also being invoked, so added an additional check in the IsValid function
* use variable for vk_tab
* remove new line before initializing dwextraInfo
* move flag check if the filterKeyboardevent function
* use windows.system.virtualkey.shift instead of defining a constant for the shift key code
* removed latest settings to use internal settings instead. Removed the validity check while still within the hotkey other than if it's tab or shift+tab
* add a function to send input to the system instead of duplicating the send input code
* remove VKSHIFT declaration
* display all shortcuts/keys except tab and shift+tab
* remove header that is no longer needed
* [Launcher/Settings] Low Level Keyboard Hooks
* [Run] LowLevel Keyboard Hook for Hotkeys
* Prevent shortcuts from auto repeating when keeping the keys pressed down
