I am not really sure if this is a bug or feature request.

Symfony version(s) affected: All

Description
When using denormalizer with array input, and mapping to type with a boolean field doesn't support to parse string values like:

"true", "on", "yes", "1" // => true
"false", "off", "no", "0", "" // => false

It is possible to go around this using attribute: AbstractObjectNormalizer::DISABLE_TYPE_ENFORCEMENT => true and using values like 0or 1 but any other string value will always be cast to true because of PHP true logic (https://www.php.net/manual/en/types.comparisons.php).

I thought I would be able to fix this issue by implementing a custom denormalizer, but type properties are not sent through denormalizers, and only the whole type.

This logic is implemented for xml/csv types:

I think the most appropriate way would be to implement a custom attribute to handle this specific case.

I will create a pull request with this implemented logic as an example of what I think can be done.
