linux-yocto: introduce 4.19 recipes

Browse Source 
Introduce the 4.19 linux kernel as the reference for LTS and eventually
LSB distros. For now, we keep the other versions around until the h/w
reference BSPs are updated and 4.20+ are available as the "latest"
kernel. This avoid updating qemu* to 4.19 as the default for a small
transition window.
