Declare this:
```yaml
services:
my_stack_of_decorators:
stack:
- class: App\ExternalDecorator
- class: App\InternalDecorator
- class: App\DecoratoredClass
```
And get this:
The PR is now ready with support for Yaml, XML and the PHP-DSL. It needs #36388, #36392 and #36389 to pass, and relates to #36390 to be DX-friendly.
The new syntax now supports composable stacks - i.e stack you can reuse in the middle of another stack.
RIP middleware, simple decorators FTW :)
From the test cases:
```yaml
services:
reusable_stack:
stack:
- class: stdClass
properties:
label: A
inner: '@.inner'
- class: stdClass
properties:
label: B
inner: '@.inner'
concrete_stack:
stack:
- parent: reusable_stack
- class: stdClass
properties:
label: C
```
This will create a service similar to:
```php
(object) [
'label' => 'A',
'inner' => (object) [
'label' => 'B',
'inner' => (object) [
'label' => 'C',
]
],
];
```
When used together with autowiring, this is enough to declare a stack of decorators:
```yaml
services:
my_processing_stack:
stack:
- App\ExternalDecorator: ~
- App\InternalDecorator: ~
- App\TheDecoratedClass: ~
```
See fixtures for the other configuration formats.

Todo:
- [x] rebase on top of #36388, #36392 and #36389 once they are merged
- [x] test declaring deeper nested stacks
