circpad: Rename circpad_machine_state_t to circpad_machine_runtime_t.

The name of circpad_machine_state_t was very confusing since it was conflicting
with circpad_state_t and circpad_circuit_state_t.

Right now here is the current meaning of these structs:

      circpad_state_t -> A state of the state machine.
      circpad_machine_runtime_t -> The current mutable runtime info of the state machine.
      circpad_circuit_state_t -> Circuit conditions based on which we should apply a machine to the circuit
