[kernel][hypervisor] Ensure singleton mutex is initialised. Due to fxbug.dev/78920, singleton mutexes are not thread-safe on their first use. In the case of the hypervisor, this can lead to the system's EL2 state incorrectly being initialised multiple times, leading to stack corruption of EL2. We temporarily work around the issue until the underlying bug is fixed by ensuring the mutex is initialised during system boot.
