[OE-core] [wic][PATCH 04/14] image-wic.bbclas: add task do_efi_populate

[Ed Bartosh]

Produce EFI artifacts by calling efi_populate function
provided by current EFI provider.

This should eliminate dependency of wic image-efi plugin
to hddimg. Instead of getting EFI artifacts from HDDDIR
it can get it from $WORKDIR/efi.
