targets: Add sample target for controller on NRF5340 bsp

This adds sample target for building NimBLE controller (blehci app)
for Nordic NRF5340. It is used by default when combine image build
is used for nordic_pca10095 bsp.

Sample target should be used as a base for creating customized targets.
This targets nordic_pca10095_net bsp, custom targets should point to
appropriate BSP.
