routing/payment_session: make NewPaymentSession take payment directly
This commit moves supplying of the information in the LightningPayment
to the initialization of the paymentSession, away from every call to
RequestRoute.

Instead the paymentSession will store this information internally, as it
doesn't change between payment attempts.

This is done to rid the RequestRoute call of the LightingPayment
argument, as for SendToRoute calls, it is not needed to supply the next
route.
