Right now these are performed in kernel/fork.c which is odd and a violation of separation of concerns, as well as preventing us from integrating this and related logic into userland VMA testing going forward. There is a fly in the ointment - nommu - mmap.c is not compiled if CONFIG_MMU not set, and neither is vma.c. To square the circle, let's add a new file - vma_init.c. This will be compiled for both CONFIG_MMU and nommu builds, and will also form part of the VMA userland testing. This allows us to de-duplicate code, while maintaining separation of concerns and the ability for us to userland test this logic. Update the VMA userland tests accordingly, additionally adding a detach_free_vma() helper function to correctly detach VMAs before freeing them in test code, as this change was triggering the assert for this.
