Support array of enums

[lstrojny]

Support array of enums, so that e.g. with ODM you can do something like this

#[Field(enumType: Variant::class]
private array $variants = [];

@lstrojny thanks for the PR! I took the liberty and retargeted this to 3.2.0 as this is a feature.

I took a quick look into ODM and if I'm not mistaken the changes here in doctrine/persistence will on its own allow combining collection and hash types with enumType?

[lstrojny]

That is correct. In fact I am using the feature branch with ODM and it just works

Also please squash your commits afterwards

Let's avoid recursion in favour of something along

Suggested change

	/** @var string[]|int[] $values */
	$values = array_map([self::class, 'fromEnum'], $enum);
	return $values;
	return array_map(fn(BackedEnum $e) => $e->value, $enum);

But compatible with PHP 7.2 :(

[lstrojny]

Done

[malarzm]

Thanks! I've PRed doctrine/mongodb-odm#2532 with a test for future us. I'll see if there are any plans for releasing 3.2.0 here.

Thanks @lstrojny! I'll be releasing 3.2.0 shortly so you may get back to stable branch ;)
