📄 Description

In the pthread affinity functions, when thread != g_curthread, we should be using ThrState::FindThread to get and lock the appropriate thread. Adding this logic fixes a potential crash in scePthreadSetAffinity, helping Need for Speed™ Heat (CUSA15081) get slightly further.
I've also added an export for posix_pthread_attr_getschedparam, as it's used by Kingdom Come: Deliverance Royal Edition (CUSA15436).
