meta-facebook: Move common recipe under facebook layer

Moved common facebook recipe under meta-facebook to support multiple
facebook platform and make use of common code across platforms.

This is just a first phase to add common layer and moved
meta-tiogapass/recipe-fbtp to ./recipe-fb. Slowly, will
move all common meta data under meta-facebook.

(From meta-facebook rev: 2769bfe7823ce0ce426f2faf463c6d91e43b6c29)
