utils: Add utils_macros: Implement ValueEnumDisplay and ValueEnumFromStr macros

Browse Source 
Add new derive macros ValueEnumDisplay and ValueEnumFromStr which can be
used to derive 'Display' and 'FromStr' for enums implementing
'clap::ValueEnum'. It helps in reducing boilerplate code and keep things
in sync.
