New architecture: Reboot UIEffectCapturedImage

[mob-sakai]

UIEffectCapturedImage has many bugs. To fix those bugs, UIEffectCapturedImage will be separated into another repository.

• [x] Create new repository
  • [ ] Transfer the issues about UIEffectCapturedImage
• [ ] Support Metal and Vulkan graphic API
  • [ ] Mipmap blurring
  • https://docs.unity3d.com/ScriptReference/Rendering.CopyTextureSupport.html

    Metal and WebGL currently do not have texture copy support

• [ ] Use ScreenCapture.CaptureScreenshotIntoRenderTexture to capture screen
  • [ ] Support Unity 2018 or later
• [x] Remove UIEffectCapturedImage from this project

This is an alternative package to UICaptureEffect component. (in preview) https://github.com/mob-sakai/UIEffectSnapshot

Please note that the API may change until stable release.
