Port yocto integration from Conan 1.x

[uilianries]

Hello!

This PR is a port of the Yocto integration from Conan 1.x docs: https://docs.conan.io/1/integrations/cross_platform/yocto.html#set-up-the-conan-layer

The meta-conan is now available for Conan 2.x, so it may worth updating the documentation too.

I think it would be better to have a full working example, that can be cloned (examples2 repo) and fully built, with a story of a full built package (like the one with conan new cmake_lib), (not necessary to force the upload to server, can be used from the cache)

Do you mean a separated PR with the example for meta yocto? Or using this integration section instead? Anyway, the idea sounds good of having a functional example.

Most of the detailed code can be in a functional example, leaving in the "Integration" section the high level description of the components, the layers, the flows, etc.
