hle: kernel: Fix service_threads access to be thread safe.
- CreateServiceThread and ReleaseServiceThread can be accessed by different threads, uses a lock to make this thread safe. - Fixes a rare crash in Pokemon Sword/Shield that can occur when a new service thread is being created while an old one is being destroyed.
