wic: add wic-tools recipe

This meta recipe is for building tools used by wic.
It allows wic to find tools in recipe specific sysroot as
all tools will be present in wic-tools sysroot.

NOTE: task do_build_sysroot is created to ensure that
sysroot is re-populated when package is built. Otherwise it will
be taken from sstate and sysroot will not be populated.

Generated wic-tools.env file for wic to be able to get values of
wic-tools variables when wic run from bitbake.

Also add dependency to grub-efi

Without grub-efi test_iso_image test case fails with this error:

AssertionError: Command 'wic create mkhybridiso --image-name
core-image-minimal' returned non-zero exit status 1:
Error: Please build grub-efi first

Fixed by adding dependency wic-tools -> grub-efi.
