ChoiceType Field should have a choice_translation_parameters option.

[VincentLanglet]

Description

There is a label_translation_parameters option (cf https://symfony.com/doc/current/reference/forms/types/choice.html#label-translation-parameters). In the same way, there is a attr_translation_parameters and help_translation_parameters.

IMHO, a choice_translation_parameters option could be great.

Example

# translations/messages.en.yaml
form.order.ok: 'I want to confirm the order made to %company%'
form.order.ko: 'I want to cancel the order made to %company%'

$builder->add('order', null, [
    'choices' => [
        'form.order.ok' => true,
        'form.order.ko' => false,
    ],
    'choice_translation_parameters' => [
        '%company%' => 'ACME Inc.',
    ],
]);

Currently,

$builder->add('order', null, [
    'choices' => [
        'form.order.ok' => true,
        'form.order.ko' => false,
    ],
    'label_translation_parameters' => [
        '%company%' => 'ACME Inc.',
    ],
]);

works, but it's weird to use a label_ option, when all the others option are prefix by choice_.
