wic: Add BootimgEFIPlugin and BootimgPcbiosPlugin

Implement the BootimgPcbiosPlugin and BootimgEFIPlugin SourcePlugin
classes.  The configure/prepare_partition() methods are implemented
using code derived from similar code in the Wic_PartData class.

These classes have the corresponding names 'bootimg-pcbios' and
'bootimg-efi', which are the names that should be used in the --source
parameters of the .wks partition commands.
