Subject: [kernel][ipc] Fix timeout wakeup ownership race

Keep thread timer ownership when timer stop races with an in-flight timeout callback, and consume IPC resources only after a waiter is resumed successfully.

Complete ownership cleanup in the generic and RT-Smart channel timeout callbacks. Add deterministic scheduler and LWP regressions for Event, Semaphore, Mailbox, Message Queue, sender, and receiver paths.
