Summary

HashMap::mapToVector allows to build a vector from an hashmap.

In Rust, an iterator can be mapped into any type, the outcome
of the iteration is decided afterwards by a collect method.

In PHP, native functions like array_map preserves the initial type.
As such, HashMap::map returns an HashMap.

The mapToVector method allows to collect the mapped values into a vector.

Test Plan

This is intended for Zed to be used with API string representation:

$response = HashMap::from($data)
    ->mapToVector(
        fn($key, $value) => "$key: " . self::toString($value)
    )
    ->implode(", ");

Unit tests are provided for our the different callback shapes.
