dtc from OUT_DIR might not be available, so use the prebuilt one instead.
Also, clean-up a little bit and follow the same logic as prebuilt make binary.

Our build/make changes break incremenetal builds with prebuilt dtb dir
(see discussion here: https://android-review.googlesource.com/c/platform/build/+/1134337/1/core/Makefile )
Instead of using the AOSP recipe, just define our own and use it by not defining
BOARD_PREBUILT_DTBIMAGE_DIR

If for whatever reason we need a prebuilt DT image,
it has to end up in target files for the signing slave.
Change BOARD_KERNEL_PREBUILT_DT to hold the path of the
prebuilt DT image, if it's going to be used.

* Fold module installation into kernel image recipe.
* Specify make argument to strip modules on installation instead of
explicitly invoking the strip tool.
* Remove support of TARGET_KERNEL_MODULES, it's a phony target thus
we're not allowed to depend on it per Android 10 restriction. It
has been useless for years anyway.
* Apply minor clean-ups.

* This fixes dirty boot image rebuilding on devices
with CONFIG_LOCALVERSION_AUTO=y and any driver
set to =m.
* Basically appending `cat include/config/kernel.release`
to modules path makes sure that our find does not
return old modules which would make cp fail with
'cp: will not overwrite just-created' message.

The kernel make command is executed in the build root. Without absolute
out paths, kernel out start with "out/" meaning it would be created in
the kernel source. Add BUILD_ROOT to the argument to ensure it's always
made in the actual out/ dir.

*) This has been deprecated by the bp mobule

LOCAL_HEADER_LIBRARIES += generated_kernel_headers
Or for soong targets:
header_libs: [ "generated_kernel_headers" ],

Currently we handle the DTBO images from start to finish, including
AVB footers, and just drop them in $(PRODUCT_OUT)/dtbo.img when done.
While this works for the most part, we are limited in what we can do
with the DTBO images. For example non-A/B device recovery images must
have a copy of the DTBO image appended to recovery (see AOSP docs:
https://source.android.com/devices/bootloader/recovery-image ). This
means that we need to pass the pre-AVB dtbo image into
BOARD_PREBUILT_DTBOIMAGE in order to let the AOSP build system handle it.
This commit reworks the way the DTBO images are built, placing them at
$(PRODUCT_OUT)/dtbo-pre.img instead and setting BOARD_PREBUILT_DTBOIMAGE
to that path so the AOSP build system can pick the images up and sign
them and append to recovery (for applicable devices).

redefining all of it inline ourselves.

* The directories used by the kernel module install rules are performed
as part of the rules in the kernel build itself. This is likely a
leftover from before kernel module install was separated.

Google added support for LTO + CFI in the Pixel 3 kernel, which requires
not only Clang but a couple of additional binaries, namely llvm-ar and
llvm-dis for IR generation. Google expects these binaries to be in PATH
according to their definitions and the build.config.common file:
https://android.googlesource.com/kernel/msm/+/android-9.0.0_r0.31/Makefile#637https://android.googlesource.com/kernel/msm/+/android-9.0.0_r0.31/build.config.common
However, kernel.mk does not add the LLVM bin directory to PATH so the
build fails because the binaries can't be found. We could add LLVM_AR
and LLVM_DIS to the make commands like CC and CROSS_COMPILE; however,
adding the bin directory to PATH is a more sustainable solution as
Google might require new binaries in the future.
Additionally, LTO needs access to the LLVMgold library so it needs to be
available in LD_LIBRARY_PATH.
Add a PATH_OVERRIDE variable that will set up PATH and LD_LIBRARY_PATH
with the bin and lib64 folders from the requested LLVM toolchain
respectively when building with Clang. This won't affect kernels that
don't use LTO like Wahoo.

Kernel source settings should always come at BoardConfig population
time so things that use the variable later don't end up pointing to
an empty or wrong variable.

tasks: kernel: Honor prebuilt kernel flag
For devices that want to use a prebuilt kernel, TARGET_KERNEL_SOURCE
would still be set to TARGET_AUTO_KDIR, meaning the build system would
still try to build the kernel if TARGET_AUTO_KDIR was present.
Setting TARGET_PREBUILT_KERNEL indicates this is not wanted, so don't
attempt to do it.

Builds that use the stock CAF device/qcom/common
generate_extra_images.mk may want to ignore this kernel.mk.
Set TARGET_PROVIDES_KERNEL_MAKEFILE to true to ignore kernel.mk.
