feat(console): accept BackedEnum as command arguments

[aazsamir]

This pull request brings possibility of using enums as command arguments.

So this will be possible

enum Type: string
{
    case JSON = 'json';
    case TEXT = 'text';
}

class MyCommand
{
    #[ConsoleCommand('cmd')]
    public function __invoke(Type $type): void {}
}

Call

./tempest cmd --type=json

in case of wrong value:

Invalid argument `invalid` for `type` argument, valid values are: json, text

And definition will be displayed as

cmd <type {json|text}>

Awesome PR, I only have a few optional style nitpicks 👍
