build: Add support for device tree in boot.img

Browse Source 
Add support for optional device tree image (dt.img)
to boot and recovery images.  Some devices use kernel device
tree and this adds the device tree image as a section within
the boot/recovery images.

Build: add DT image variable to Makefile

DT image variable is currently present in
generate_extra_images.mk.This file is moved to
build/tasks to support persist image generation
during parallel make. As build/tasks is called
at the end of Makefile, DT image variable is not
available for other images generation like boot and
recovery. Adding this variable in Makefile ensures
the variable is defined before usage

CRs-fixed: 548299

Fix case where boot/recovery.img were being built with wrong params.

The boot and recovery images  now get built using the same params during ota package
generation as during a normal build.

Fix the extra dt.img compilation issue.

Add support for optional device tree image (dt.img)
for device that doesnt have TARGET_BOOTIMAGE_USE_EXT2

releasetools: Store and use the dt image file through target files

Target files packages may be used for signing images separate from the
build process. Store the device tree image file in the target files
package so it can be used during the signing process.
