feat: handle type importation from interface

[romm]

Allows usage of @phpstan-import-type and @psalm-import-type from interfaces:

/**
 * @phpstan-type SomeAlias = array{foo: string, bar: int}
 */
interface InterfaceWithPhpStanLocalAlias { }

/**
 * @phpstan-import-type SomeAlias from InterfaceWithPhpStanLocalAlias
 */
final class SomeClass
{
    /** @var SomeAlias */
    public $value;
}

(new \CuyZ\Valinor\MapperBuilder())
    ->mapper()
    ->map(SomeClass::class, [
        'foo' => 'bar',
        'bar' => 42,
    ]);

Fixes #353
