Close for MM 13.0.0

The final fix for this in Rasberrypi4 and H3 requires also this change:
https://gerrit.automotivelinux.org/gerrit/c/AGL/meta-agl-demo/+/27300/1
The reason for this (and https://lf-automotivelinux.atlassian.net/browse/SPEC-4290#icft=SPEC-4290) is hangs on calls to eglSwapBuffers, internally calling wl_display_dispatch_queue. It seems the presentation feedback implementation is not working. The solution is disabling VSync in Chromium for now, passing --disable-gpu-vsync
The new issue for fixing the VSync problem is reported at https://lf-automotivelinux.atlassian.net/browse/SPEC-4310#icft=SPEC-4310.

Gave it a test but I don't see any progress, added two debug log files. debug.txt is when normally booting up, debug_stop_start.txt is after I manually stop wait until WAM stops homescreen then start it the session again.
Note that in the normal debug.txt I don't any see any 5 delay at all.

Review request: https://gerrit.automotivelinux.org/gerrit/c/AGL/meta-agl-demo/+/27276/1 (for workaround)

Provisionally I will raise the homescreen launch wait to 5 seconds for marlin release. Then move to fix the issues with WAIT_FOR_HOST_SERVICE.

Probably this will be fixed by SPEC-4252, but thought on still documenting it.
Compositor says that it never gets the ready request or it gets any panel or background request. Only a temporary surfaces is being created:
Jun 29 03:06:54 h3ulcb agl-compositor[638]: [03:06:54.280] Added surface 0xaaaae4173620, app_id (null) to pending listAttached WebAppMgr log and current running aps for journaltctl.
Note that this does not happen always, some boots do bring up the apps.
