EFI: Make installer EFI aware

[YOCTO #1919]

Create a basic EFI installer script modeled after the existing installer
and add it to a new initramfs-live-install-efi recipe. Update the
init-live.sh script to distinguish between LABEL=install and
LABEL=install-efi and select the appropriate script. Add the efi
installer to core-image-minimal-initramfs.

Update grub-efi.bbclass to use "LABEL=install-efi" when it detects a
label of "install". This is clearly not ideal, but a proper fix would
involve decoupling the LABELS assignment from the image-live.bbclass
usage of SYSLINUX_LABELS. We should be able to address that in a
follow-on clean-up series.

V2: Include missing initramfs-live-install-efi_1.0.bb
V3: Rebase after Radu's console_params fix
