The logic is practically intact and is the following:
1. Use any host installed llvm/clang in the path in case
ZEPHYR_TOOLCHAIN_VARIANT=llvm is requested alone.
2. This can be further restricted with TOOLCHAIN_HOME.
3. And can be further overridden with CLANG_ROOT_DIR,
like previously.
So, only the unconditional restriction to /usr is lifted.
Together with fixing the unconditional set of TOOLCHAIN_HOME
by host tools for non-toolchain needs, this makes the logic
more flexible.
Now, after the logic is controllable by TOOLCHAIN_HOME, 3)
might be an extra, but is left intact for backward compatibility.

support DeviceTree sources and bindings being placed in out-of-tree

APPLICATION_SOURCE_DIR and out-of-tree directories conform to using
the same DTS_ROOT concept and directory structure.

While this race seems unlikely and harmless let's play it safe and
implement the usual solution: temporary file + atomic rename.
The race is unlikely and maybe even harmless because:
- Only sanitycheck seems to invoke cmake concurrently.
- Users rarely delete their ~/.cache/zephyr/ToolchainCapabilityDatabase/
- All concurrent cmake processes write the same, single byte to the same
files.
- Creating a single byte is at least very fast, so extremely short
window for others to read an empty file.

PR #14776 / commit 915a353255 changed function
zephyr_library_compile_options() to use MD5 instead of RANDOM for build
reproduction reasons. As later predicted by Sebastian Bøe in the PR
(thx), the names generated for these pseudo-libraries won't be unique
anymore if the exact same flag gets added more than once.
To reproduce the issue, simply add the following two lines in some
CMakeLists.txt file like samples/hello_world/CMakeLists.txt:
zephyr_library_compile_options("-Dfubar=barfu")
zephyr_library_compile_options("-Dfubar=barfu")
cmake will then fail like this:
CMake Error at zephyr/cmake/extensions.cmake:403 (add_library):
add_library cannot create target
"options_interface_lib_e689fdb7eb15d801c2f95dd61301fc5e" because
another target with the same name already exists. The existing
target is an interface library created in source directory
"zephyr/samples/hello_world". See documentation for
policy CMP0002 for more details.

1. To support being called multiple times, the function
zephyr_library_compile_options() uses unique
options_interface_lib_${random} names. These only need to be unique, not
random. So replace them with a simple MD5 hash of the ${item} argument.
To reproduce quickly run:
sanitycheck -b -p qemu_xtensa --tag shell
... a few times and compare the output directories.
This bug sits for now at the top of the list of build reproducibility
issues the most bizarre and difficult to root cause. When running
sanitycheck over a large sample of configurations it was affecting
only qemu_xtensa/**/zephyr/arch/arch/xtensa/core/startup/Makefile
files (and their corresponding CMakeFiles/TargetDirectories.txt),
randomly ordering the following three Make targets and only these
three: rebuild_cache, edit_cache, arch__xtensa__core__startup.
The key to root causing was cmake --trace-expand which prints the random
string.
2. generate_unique_target_name_from_filename() also generated a random
string for the same uniqueness reason. This one was easier to root cause
and reproduce with: sanitycheck --tag gen_inc_file

Currently, the Kconfig.modules file is placed in the build directory
relative to the CMake "project". But technically, the file is not
project-specific, but global, or build-directory specific.
So we move it up one level to the CMAKE_BINARY_DIR instead. Currently,
there is only one project, so this change has no effect, but this
enables us to have multiple projects in the future, which again
enables multi-image builds.
