3d75cc1bd2 libcamera: bound_method: Support connection types
Support all connection types in the BoundMethodBase::activePack()
method. To support this, add a semaphore to the InvokeMessage to signal
delivery.

d5d7b71521 libcamera: object: Add an asynchronous method invocation method
Add a helper invokeMethod() to the Object class that allows asynchrnous
invocation of any method of an Object instance. Asynchronous invocation
occurs when control returns to the event dispatcher of the target
object's thread, in the context of that thread.

To support this, generalise the SignalMessage implementation to support
automatic deletion of the associated BoundMethod, and rename the message
to InvokeMessage to reflect the more generic purpose.

f83820a5d1 libcamera: bound_method: Decouple from Signal implementation
To make the BoundMethod classes more generic, replace direct access to
private member from Signal classes with accessors or helper functions.
This allows removal of friend statements from the BoundMethod classes.

0e65ed8145 libcamera: signal: Split Slot implementation to reusable classes
Move the Slot* classes to bound_method.{h,cpp} and rename them to
Bound*Method*. They will be reused to implement asynchronous method
invocation similar to cross-thread signal delivery.

This is only a move and rename, no functional changes are included.
