The check for official builds now only affects the case where a prebuilt
kernel was actually used, not the case where a device builds a kernel
from source as normal.
The check has also been turned around so that it only fails the build if
it's actually an official build, not an unofficial one.

* TARGET_FORCE_PREBUILT_KERNEL should be useful when you don't have ready kernel sources (OEM releasing broken sources or releasing them lately)
* It lets you use kernel sources for userspace generated headers (generated_kernel_headers) while keeping using prebuilt kernel
* Keep in mind that generated kernel headers may not align with the ABI of kernel you're including
* This commit also partially revert commit a836d79, where TARGET_KERNEL_SOURCE would have been unset if TARGET_PREBUILT_KERNEL was defined (we already check in kernel.mk if kernel sources are present anyway)

Mini documentation:
List the names of boot modules in BOOT_KERNEL_MODULES to add them
to vendor_boot.
All modules still end up in their primary location (normally
vendor/lib/modules). Boot modules will be kept here as duplicates.
The list of boot modules is then depmod'ed and copied to the
vendor ramdisk.
The file modules.load is created from
BOARD_$(IMAGE)_KERNEL_MODULES_LOAD as the ordered list of modules
to be loaded form that location, either parsed by a modprobe script
or by init itself (only boot modules)
When using vendor_boot modules, vendor/lib/modules/modules.load
should list all modules but boot modules.
Also don't clear the output directory, because one might want to
push a modules.blocklist there.

* We're having a race with the kernel module build and vendor.img
generation, and sometimes when vendor.img wins it won't include
any modules in the image, which leads to all sorts of breakage

- The goal of specifying kernel image name was to whether kernel needs
appended dtb or not, which is not something required if the kernel is
prebuilt

* The new refactored function doesn't work with shell expanded
variables, like our $$modules.
* This is the _easy_ fix.
A proper fix would imply generating the module list into a make variable
from the shell variable, but with kati that looks unfeasable (to me...)

* A simple "make kernel" or incremental system build
always triggers a complete kernel recompilation,
even though the kernel sources were unchanged
* The reason is because .additional_config is always
considered new and invalidates the .config file,
forcing the kernel to rebuild itself every time
* Instead, prevent the /dev/null and KERNEL_OBJ dependencies
having irrelevant timestamp changes with an empty variable
* Command "make kernel" takes 3 seconds versus 40s before

* Remove the separate dtbo.mk task and merge it
in kernel.mk
* Merge in-kernel and separated DTBO image generation

* This makes it use the latest source built dtc instead of the prebuilt,
which is too old for coral/4.14
* Would be best to have it use the in-kernel DTC though,
as that should always work for that particular kernel.
* When OUT_DIR_COMMON_BASE isn't set, this path is relative (i.e. out/),
so append $(KERNEL_BUILD_OUT_PREFIX) to account for that.

* On devices using vendor_overlay it could be useful
to be able to re-name the installed modules to
match the ones in vendor
-> An example is QCOM techpack where default module
name in kernel doesn't match installed module
name

If the prebuilt directory is set, then the AOSP commands get activated,
which will conflict with ours, so just disable ours if the prebuilt
directory is set.

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

Previously, this would be a full compile prefix
(e.g. prebuilts/gcc/.../bin/aarch64-linux-gnu-). Since we're adding
this to PATH, it only needs to be prebuilts/gcc/.../bin.
Also remove the extra /bin/ added by kernel.mk.

* 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.

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 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.

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).

kernel modules being enabled as a kernel feature.

* 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.
