Graphic stack bringup

To get graphic stack working in 3.0 some things had to be fixed and a gralloc implementation had to be backported from 3.1.

+display: Use temporary qemuarm implementation
+
+OpenHarmony 3.0 requires two display components:
+
+- hdi_display_device
+- hdi_display_gralloc
+
+none of which is available for qemuarm standard system. Therefore we have to
+provide mock implementation of non-essential hdi_display_device and a proper
+implementation of hdi_display_gralloc without which OpenHarmony graphic stack
+will not work.
