Always do thread safety checks when calling async_fire

[bdraco]

needs

• Rename bus._async_fire to bus.async_fire_internal #116027
• Add debug mode to catch unsafe thread operations using core helpers #115390
• Fix non-thread-safe operations in media_extractor #116065
• Fix non-thread-safe operations in html5 #116068
• Fix non-thread-safe operation in harmony #116070
• Fix non-thread-safe operations in wake_on_lan #116069

Proposed change

Since almost all core events call async_fire_internal (after #116027) now its worth the performance tradeoff to check if the thread is correct in async_fire.

See discussion #115390 (comment)

In a followup I will add the check in async_register and async_unregister and switch them to use _internal since currently they can still unsafely register a service from a thread since the check doesn't happen until the service registered event is fired. It will also give devs a better hint as to where things went wrong
