[nrf fromtree] devicetree: add DT_NODE_HAS_STATUS_OKAY

We already have `DT_HAS_COMPAT_STATUS_OKAY` and
`DT_NUM_INST_STATUS_OKAY`, it seems intuitive to assume that
`DT_NODE_HAS_STATUS_OKAY` exists, so much so that it was used
before it's implemented.

This patch implements `DT_NODE_HAS_STATUS_OKAY`, which is
equivalent to: `DT_NODE_HAS_STATUS(<node_id>, okay)`

Added test for it in `tests/lib/devicetree/api`
