bitbake-layers: adapt force option to not use tinfoil

Fixes [YOCTO #15417]

When a layer adds a new dependency after it was added to a conf, it can not be
removed w/o this dependency in the setup. Even the dependent layer can not be
added, as the tinfoil setup will fail.
Adapt --force to not perform the tinfoil at all, the use will be at own risk,
i.e. the added layers might not parse properly afterwards.
This is not merged into the force option with -F as it even changes the loading of
plugins from other layers and is hence even more invasive as force. Instead
force can now be speciefied multiple times and is counted.
