dts: bindings: nrf-vpr: Allow specifying pins and not using launcher

Add possibility to use pinctrl to configure pins that should be assigned
to nRF VPR coprocessors and also provide a way of preventing activation
of the nordic_vpr_launcher driver for an enabled VPR so that it can be
supplied with the code to execute and launched in a custom way.
