[meta] Replace lazy service proxy generation with service closures

Problem/Motivation

As discussed in 📌 DX: Creating lazy services is too difficult/obscure/bespoke/brittle Active the DX for our current lazy service proxies is poor. We tried using symfony lazy services in 📌 Deprecate Drupal ProxyBuilder in favor of Symfony lazy services Closed: won't fix however that was not possible due to:

Sadly SF uses eval for the proxy classes which at least I can't see working with our serialized container solution

However we can now use service closures to lazy-load services which are supported by our serialized container.

Steps to reproduce

Proposed resolution

Replacy services tagged 'lazy' with service closures.

Prefer using autowiring and the #[AutowireServiceClosure] attribute over the !service_closure yaml command where possible.

https://symfony.com/doc/current/service_container/autowiring.html#genera...

This requires changing the constructor signature and adding a new method to invoke the closure like so:

Before:

public function __construct(
  protected CronInterface $cron,
) {}

Service definition:

services:
  my_service:
    class: Foo\Bar
    arguments: ['@cron']

After:

public function __construct(
  protected \Closure $cronClosure,
) {}


protected function getCron(): CronInterface {
  return ($this->cronClosure)();
}

Service definition:

services:
  my_service:
    class: Foo\Bar
    arguments: [!service_closure '@cron']

Autowiring approach

Before:

public function __construct(
  protected CronInterface $cron,
) {}

Service definition:

services:
  my_service:
    class: Foo\Bar
    autowire: true

After:

public function __construct(
#[AutowireServiceClosure('cron')]
  protected \Closure $cronClosure,
) {}


protected function getCron(): CronInterface {
  return ($this->cronClosure)();
}

Service definition:

services:
  my_service:
    class: Foo\Bar
    autowire: true
