Proposal: Support for declaring the cursor for a XAML UI Element

Summary

In WPF, you can easily change the cursor of an element. However, in WinUI you have to subscribe to the OnPointerEntered and OnPointerExited events and change the shown cursor accordingly using WinRT APIs in a UWP CoreWindow or Win32 APIs in a Desktop HWND or use the XAML extensions from Windows Community Toolkit. WinUI should offer a built-in way to change the cursor.

Rationale

Many developers who are familiar with WPF expect a straightforward way to change the cursor of any element. Although devs can use Windows Community Toolkit, I believe that WinUI should offer it built-in. This will also allow C++ devs to change the cursor within XAML markup. It will also be better if we could define custom cursor in XAML without code-behind (Refer this link).

Scope

Capability	Priority
This proposal will allow developers to set the mouse cursor for a UI Element using XAML markup	Must
This proposal will allow developers to set the mouse cursor for a UI Element from code-behind without pointer events	Must
This proposal will allow developers to define and use custom cursors in markup without code-behind	Could

Important Notes

UIElement should have a Cursor property of CoreCursor. It should also work with WinUI Desktop Apps.

[Felix-Dev]

This should be integrated into proposal #506 which mentions custom cursors and in point 4) the addition of a Cursor API.

Lets track it through #506. @JaiganeshKumaran please feel free to add information to that proposal if needed. Thanks!
