libcamera: thread: Support dispatching messages to main thread

Threads contain message queues and dispatch queued messages in their
event loop, in Thread::exec(). This mechanism prevents the main thread
from dispatching messages as it doesn't run Thread::exec().

Fix this by moving message dispatching from Thread::exec() to
EventDispatcher::processEvents().
