The fuel gauge API uses separate get/set property structs to indicate what
properties are readable or writable. This lead to duplication in property
names and potential confusion for new users of the API. See issue #61818.
In addition to above, drivers already determine at runtime if a property is
supported for read or write actions.
Join the get/set fuel gauge property structs as a single struct.
