device property: Split property reading bool and presence test ops
The fwnode/device property API currently implement
(fwnode|device)_property_read_bool() with (fwnode|device)_property_present().
That does not allow having different behavior depending on the backend.
Specifically, the usage of (fwnode|device)_property_read_bool() on
non-boolean properties is deprecated on DT. In order to add a warning
on this deprecated use, these 2 APIs need separate ops for the backend.
