[nrf fromtree] dts: nordic: Add Channel Sounding support to nrf-radio

- Added `cs-supported` property to nrf-radio devicetree
- Added `HAS_HW_NRF_RADIO_CS` Kconfig option which is set if
`cs-supported` property is enabled
- Enabled `cs-supported` property for nrf54-series devices
- Disabled `cs-supported` on nrf54l15bsim because it is not
yet supported
