prop_tree: Multiple API enhancements to uhd::property

- Added desired and coerced values and accessors to property
- Added support to register desired subscribers
- set APIs don't reallocate storage for a property value
- Renamed callback method registration APIs
- Registering 2 coercers or publishers for a property will throw
- Registering a coercer and a publisher for the same property will throw
