Prepare 2.12 release

Improve performance for supporting Laravel 8.77+ cast attributes (bar…

…ryvdh#1292)

barryvdh#1289 calls `getReturnType` for every method on every model, which in
turn calls `getReturnTypeFromDocBlock` which has this code:
```php
$phpDocContext = (new ContextFactory())->createFromReflector($reflection);
```
Extracting the docblock is super slow, always has been. Now that we do
this for every method, this adds up a lot.

Performance on a private commercial project _before_ barryvdh#1289 was introduced:
```
$ time ./artisan ide-helper:models --write --reset >/dev/null

real	0m2.857s
user	0m1.835s
sys	0m0.129s
```
After barryvdh#1289 :
```
$ time ./artisan ide-helper:models --write --reset >/dev/null

real	0m54.147s
user	0m47.132s
sys	0m1.047s
```

However, in this case we **do not need** the phpdoc fallback (which is
legitimate and by design for many other cases), because also the Laravel
implementation only works by inspecting the _actual type_, see
https://github.com/laravel/framework/blob/e0c2620b57be6416820ea7ca8e46fd2f71d2fe35/src/Illuminate/Database/Eloquent/Concerns/HasAttributes.php#L570-L575
```php
$returnType = (new ReflectionMethod($this, $method))->getReturnType();

return static::$attributeMutatorCache[get_class($this)][$key] = $returnType &&
            $returnType instanceof ReflectionNamedType &&
            $returnType->getName() === Attribute::class &&
            is_callable($this->{$method}()->get);
```

This side-stepping the phpdoc parsing a) still works correctly and b)
brings us back to the previous performance characteristics:
```
time ./artisan ide-helper:models --write --reset >/dev/null

real	0m2.987s
user	0m1.915s
sys	0m0.120s
```
