Update the DrawingIsland sample using public WASDK 1.5 APIs.

Renamed C++ version into CppTest and created parallel C# / NET CsTest version.

The Cs version is not working correctly with CsWinRT and .NET 8 yet. To get the C++ projects to successfully build, unload the Cs projects from the VS solution:
- DrawingCsTestApp
- DrawingCsTestPackage
- DrawingIslandCsProjection

Thanks to Manodasan, this fixes the CsWinRT support. :-)

Resolve most #if/#endif blocks for either support or not.
Remaining:
- Mica on Win11
- Improve Accessibility

Move feature areas into sub-structs to partition. (Will continue this more.)
Fix word-wrapping at 100 columns.

Members are now in a more readable order, members that are not used have been removed, and everything is better partitioned.

The experimental sample has now been completely superseded by the new WASDK 1.5 public DrawingIsland sample that shows both C++ and C# callers.

2. Execute file loading / bitmap decoding parallel.
3. Make more common functions to improve readability.

The Cs projects run down-level to RS5. They should not require Win11.

* Add RecreateGraphicsDevice method.

* Implement TextRenderer::RecreateDirect2DDevice.

* Catch device-removed exceptions.

* Add DeviceLostHelper class.

* Handle device lost event.

* DeviceLostHelper cleanup.
