Add methods to FwNode for reading several firmware property types like strings, integers and arrays. Most types are read with the generic `property_read` method. There are two exceptions: * `property_read_bool` cannot fail, so the fallible function signature of `property_read` would not make sense for reading booleans. * `property_read_array_vec` can fail because of a dynamic memory allocation. This error must be handled separately, leading to a different function signature than `property_read`. The traits `Property` and `PropertyInt` drive the generic behavior of `property_read`. `PropertyInt` is necessary to associate specific integer types with the C functions to read them. While there is a C function to read integers of generic sizes called `fwnode_property_read_int_array`, it was preferred not to make this public.
