image_type_tezi.bbclass: add dtoverlays support
Introduce TEZI_EXTERNAL_KERNEL_DEVICETREE and
TEZI_EXTERNAL_KERNEL_DEVICETREE_BOOT variables. First one provides the
list of overlays copied to boot partition (by default all overlays are
copied), the second one sets the list of overlays that should be loaded
during boot time (listed in ${bootfs}/overlays.txt).
TEZI_EXTERNAL_KERNEL_DEVICETREE_BOOT defaults to be empty.

(cherry picked from commit c648af29199e2f8dedcaf6b7c3c61a2dcf6a579b)
