mm/vma: convert as much as we can in mm/vma.c to vma_flags_t

Browse Source 
Now we have established a good foundation for vm_flags_t to vma_flags_t
changes, update mm/vma.c to utilise vma_flags_t wherever possible.

We are able to convert VM_STARTGAP_FLAGS entirely as this is only used in
mm/vma.c, and to account for the fact we can't use VM_NONE to make life
easier, place the definition of this within existing #ifdef's to be
cleaner.

Generally the remaining changes are mechanical.

Also update the VMA tests to reflect the changes.
