libcamera: Use simpler Signal::disconnect() function

When disconnecting a signal from a receiver, it is usually not necessary
to specify the receiver's slot function explicitly, as the signal is
often connected to a single slot for a given receiver. We can thus use a
simpler version of Signal::disconnect() that takes a pointer to the
receiver object only. This reduces code size, as the disconnect()
function is a template function.
