UnifiedHMI: Update SRCREV for RVGPU and virtio-loopback-driver, and upgrade mesa-virtio.

- OSS RVGPU update: Support for xdg_shell.

- OSS virtio-gpu-driver update: Simplify directory structure, not use cmake.

- Recipe updates:

  1, Update SRCREV for RVGPU. Since RVGPU now supports xdg_shell in OSS, the patch enabling xdg_shell has been removed.

  2, Remove the agl-shell-desktop interface because it is planned to be phased out.

  3, Upgrade the base mesa for mesa-virtio from 18.2.0 to 20.3.5. Remove patches that were used with mesa-18.2.0. We are exploring ways to run it with the newer mesa.

  4, Update SRCREV for virtio-loopback-driver.

  5, Update meta-data for patches of RVGPU and virtio-gpu-driver. The content of the patches remains unchanged.

We are planning to support a gRPC protocol interface for RVGPU.

 Prepare two images, one as the Sender and the other as the Receiver.
 It is necessary for the Sender and Receiver to be within the same network.

 After completing these steps, the Weston screen from the Sender will be transferred and displayed on the Receiver using rvgpu-proxy and rvgpu-renderer. You can verify that everything is functioning properly by launching wayland applications on the Sender side, such as:
 ```
-$ <WORKDIR>/run_remote_app.sh weston-simple-egl -f
+$ weston-simple-egl -f
 ``` 
 
 You can also verify the touch or keyboard operation support of the RVGPU by using app such as 
 ```
-$ <WORKDIR>/run_remote_app.sh weston-smoke
-$ <WORKDIR>/run_remote_app.sh weston-editor
+$ weston-smoke
+$ weston-editor
 ```
 **Note**: There are known issues with mouse, such as the cursor becoming invisible and occasional flickering of a green screen.
 
-**Appendix**:  
-- You can freely change the display position of the transferred surface in rvgpu-renderer by w option, such as
-  ```
-  rvgpu-renderer -b 1080x1500@0,0 -p <Port_Number> -w <x>,<y>
-  ```
-  The coordinates `<x>,<y> = 0,0` represent the top-left corner, and the default position is `0,250`.

+**Appendix**  
 - By building the RVGPU on Ubuntu, it is possible to enable bidirectional remote rendering between the agl-demo-platform and Ubuntu.
