New meta-egvirt layer for AGL virtualization

New meta-egvirt layer for AGL virtualization

meta-egvirt is the AGL Virtualization Expert Group (EG-VIRT) layer. It is
intended to be used to design, test, implement and assess virtualization
technologies (containers, hypervisors, system partitioners and other solutions)
for AGL ARMv8 and Intel platforms.

The primary hardware target of such work is for the time being the Renesas
R-Car M3 development platform (ARMv8). Other solutions will be added in future,
depending on their availability and on the community interest.

Changelog: added file 50_bblayers.conf.inc as a generic agl-egvirt feature

Bug-AGL: SPEC-787
