da1469x_dk_xxx: Add VBUS handling 

Two BSPs with DA146xx MCUs are now adopted to
VBUS handling changed introduced to dcd_da146xx driver.

da14695_dk_usb as bus-powered devices informs driver that
VBUS is present at startup.

da1469x-dk-pro has VBUS change interrupt handler that
informs driver about VBUS changes.
