Lioncash 75603b005b process/vm_manager: Amend API to allow reading parameters from NPDM metadata
Rather than hard-code the address range to be 36-bit, we can derive the
parameters from supplied NPDM metadata if the supplied exectuable
supports it. This is the bare minimum necessary for this to be possible.

The following commits will rework the memory code further to adjust to
this.
