bootstd: Add an implementation of distro PXE boot
Add a bootmeth driver which handles distro boot from a network device, so
we can boot a bootflow using this commonly used mechanism.
In effect, this provides the same functionality as the 'pxe' command
and shares the same code. But the interface into it is via a bootmeth.
For now this requires the 'pxe' command be enabled. Future work may tidy
this up so that it can be used without CONFIG_CMDLINE being enabled.
