Kernel: See below.

- Fix ACPI.
- Parsing SDT correctly now.
- Fix ke_runtime_check line endings.
- Update Kernel heap magic and add padding to header.
- Document Code Manager add limit for process teams.
- Add execute_from_image for Code Manager.
- Add loop for scheduler inside RuntimeMain.
- Set SMP core to 4 for testing purposes.
- Check for ACPI 2.x+
