hle: kernel: KScheduler: Fix deadlock with core waiting for a thread lock that has migrated.
- Previously, it was possible for a thread migration to occur from core A to core B.
- Next, core B waits on a guest lock that must be released by a thread queued for core A.
- Meanwhile, core A is still waiting on the core B's current thread lock - resulting in a deadlock.
- Fix this by try-locking the thread lock.
- Fixes softlocks in FF8 and Pokemon Legends Arceus.
