* [#17244](https://github.com/apache/nuttx/pull/17244) [!] sched/event: removed event_tickwait_wait() and added TSTATE_WAIT_EVENT
   This PR contains breaking changes for event implementation to improve its performance, safety and make its api cleaner and easier to use
   Change summary:
     Refactors the event module by removing its dependency on semaphores and separate wait objects, and introduces a new task state 
     TSTATE_WAIT_EVENT to simplify scheduling and improve maintainability.
   Details:
     1. Remove semaphore dependency
     Reason:
     - Semaphore objects consume more memory than necessary for event synchronization.
     - Semaphore interfaces are relatively complex, involving global locks and logic that exceeds
     the needs of the event mechanism.
     Benefit:
     - Simplifies the event module and reduces runtime and memory overhead.
     2. Remove wait object dependency
     Reason:
     - Wait objects introduce additional memory usage.
     - The current design either uses a local wait object in the waiting task (which is unsafe because the posting task also accesses it)
     or requires users to define global wait objects and call event_tickwait_wait(). This leads to complicated and error-prone usage.
     - By removing wait objects, the event module can be implemented more cleanly.
     Benefit:
     - Simplifies API usage.
     - Improves safety and code maintainability.
     3. Introduce TSTATE_WAIT_EVENT and move the scheduling list to the event object
     Reason:
     - Makes the event module implementation more concise.
     - Allows the scheduler to handle tasks blocked on events more flexibly in special cases (e.g., task deletion).
     Benefit:
     - Improves modularity and better integrates event handling with the scheduler.
     Impact

     This change streamlines the event mechanism by eliminating unnecessary abstractions, reducing memory footprint, 
     and improving the clarity of both the implementation and external API, no impact to other nuttx functions

* [#17339](https://github.com/apache/nuttx/pull/17339) ! driver/timers: Remove oneshot callback, args and tick-based API. [ClockDevice Part III]
     Summary
     This is Part III of the #17276. In this PR, we
         Removed the callback and args for all oneshot timer drivers and let the upper-half manage the callback and args.
         Removed all tick-based oneshot drivers and provide the temporary fallbacks.
     The next part is #17338.
Impact
     These code commits affect the timing subsystem, as well as the following architecture:
         arm-v7a/arm-v7r/arm-v8r
         arm-v8a
         risc-v
         tricore
