meta-core/recipes-graphics/mesa: Backport a fix from 22.2.5
This adds 0001-virgl-don-t-a-use-staging-when-a-resources-created-w.patch which is a backport from mesa 22.2.5 as a tentative fix for running on virgl on the x86 platform. This issue seems have been fixed 22.2.4 and 22.2.5, but the original change was initially quite a long time before in 22.0.X and we seem to be using 22.0.3. This also seems to affect Xen when updating it from 4.16 to 4.18.

+Subject: [PATCH] virgl: don't a use staging when a resources created with the
+ shared flag
+
+There seems to be a problem with running firefox by using Xwayland that
+results in a shared resources being not always tagged as using staging.
+
+As a result one process tries to map the resource that was allocated as
+one that uses staging without actually using the staging resource, and
+hence the mapped range only accounts for the small region that we have
+to allocated because a zero-allocation doesn't work, but the application
+mapping the resource assumes that a properly sized range is mapped, and
+consequently this results in invalid memory access.
+
+To work around this issue disable creating staging for resources that
+are created by using shared binding. It is not clear to me whether this
+is the best fix, but it seems to quell the issue.
