Cross-platform mechanism for setting the mouse cursor

[mikeparker104]

Provide the ability to change the mouse cursor when hovering over a View on desktop platforms.

Such an API would provide a way to set the cursor type for a given View using a cross-platform enum of cursor types available on both macOS and Windows. A key considerations is the selection of cursor types is limited on MacCatalyst compared to AppKit. However, it's technically possible to set the unsupported/undocumented AppKit cursor types using selectors e.g., Cocoa predefined resize mouse cursor?.

The cross-platform cursor type enum might include the following values:

public enum CursorType
{
    Arrow,
    Hand,
    Help,
    IBeam,
    NotAllowed,
    Wait,
    Crosshair,
    UpDown,
    LeftRight,
    LeftUpRightDown,
    LeftDownRightUp
}

Each cross-platform CursorType value would need mapping to the respective platform-specific cursor that is the best fit. For example:

CursorType	Mac	Windows
Arrow	arrow	Arrow
Hand	pointingHand	Hand
Help	_helpCursor	Help
IBeam	IBeamCursor	IBeam
NotAllowed	operationNotAllowed	UniversalNo
Wait	_waitCursor	Wait
Cross	crosshair	Cross
UpDown	resizeUpDown	SizeNorthSouth
LeftRight	resizeLeftRight	SizeWestEast
LeftUpRightDown	_windowResizeNorthWestSouthEastCursor	SizeNorthwestSoutheast
LeftDownRightUp	_windowResizeNorthEastSouthWestCursor	SizeNortheastSouthwest

It would be great to explore what this API could look like as part of this toolkit and whether the cursor could be set via an attached property and/or behaviour. Any input is appreciated.
