Define CONFIG_64BIT for LP64 target

Linux kernel uapi headers use CONFIG_64BIT flag. We need to define that if
__LP64__ flag is defined.

build: Add support for device tree in boot.img

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

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.

enable sdiv support in ART

ART looks for TARGET_CPU_VARIANT to determine hardware
instruction set support. QCOM chipsets set TARGET_CPU_VARIANT
as "generic", so we add it to ART's look-up list.

Fully expand eng/debug/tests module install files

When including eng, debug and tests modules that are tagged
using LOCAL_MODULE_TAGS, fully expand the install file list
from just the tagged module to all the module's INSTALLED
list.  This allows auto-generated files such as dex preopt
odex files tagged under the module's INSTALLED list to be
included.  This also makes the behavior of specifying a
module as debug using LOCAL_MODULE_TAGS to be the same as
specifying it as PRODUCT_PACKAGES_DEBUG when building
for userdebug or eng variant.

Allow override of DEX_PREOPT_DEFAULT

Allow device-specific override of DEX_PREOPT_DEFAULT value
rather than dependent on the number of runtimes supported
by the system.  This allows force generation of
non-stripped packages even when dex pre-opt is enabled
with only 1 runtime.
