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.
