soc/intel: Retype `CnviBtAudioOffload` devicetree option

The `FORCE_ENABLE` and `FORCE_DISABLE` names do not match what FSP UPDs
say, and can be confused with the `PchHdaTestPowerClockGating` UPD.

Replace the enum with a bool, and drop the confusing names. Note that
the enum for Ice Lake was incorrect, but no mainboards used the option.
