Mark System module procedural hooks as converted

Problem/Motivation

Follow-up from #3494908: Set skip procedural scanning for all modules in core. Let's make the changes we need to make to mark the remaining modules.
Modules that implement hooks that cannot be converted we use the #[StopProceduralScan] Attribute.
This is for system.

Steps to reproduce

Proposed resolution

Add #[StopProceduralScan] Attribute to modules that have hook_requirements, hook_hook_info or hook_module_implements_alter
Move procedural hooks to top of files that must remain

If there is not already a services file create it
