Unified HMI: initial commit

This is the initial commit for RVGPU of Unified HMI.

`Unified HMI` is a common platform that promotes UX innovation
in integrated cockpits and enables flexible information display
from various applications across multiple displays.

`RVGPU` is a client-server based rendering engine
that creates 3D commands on a client device, sends them to a server
for GPU rendering, and displays the results.

- create new layer, meta-uhmi
- create sub-layer, meta-rvgpu
- add 1 feature to enable basesystem, agl-rvgpu

+Subject: [PATCH] Add stride status to virtgpu_3d_transfer_to_host
+
+The gallium driver in mesa-18.2.0 does not support kernel-5.10 stride
+variable definitions. We are currently working on an update to mesa,
+but currently need to use mesa-18.2.0, so the stride variable needs
+to be defined.
+
+Upstream-Status: Inappropriate [embedded specific]
