refactor(osal): replace NuttX internal APIs with POSIX APIs

Browse Source 
Replace nxsched_self() and nxsched_set_priority() with
standard POSIX sched_getparam() and sched_setparam() in
usb_osal_thread_schedule_other().

This improves portability and follows POSIX standards for
thread priority management.
