[Test] (MG_Test, MG_Test/Backend): pin BackendObject's EGL surface bookkeeping before it moves

Browse Source 
- BackendObjectEglStateTest: 90 cases over the display, the surface records, the active surface, each thread's binding, the capability probe, the deferred destroy and the locking, driven through a double with no device; every hook is logged with its thread and the state it saw from inside
- the double reads the base's state only in a few accessors, so moving the bookkeeping re-points them and no case
- checked against 235 hand-made mutants of the bookkeeping: every one is caught except those that cannot change an outcome, one that is undefined behaviour and three that only drop an outer lock
