When building with asan enabled on windows tools such as
msgfmt will run before the install phase which normally
copies the required asan dlls next to the binaries preventing
msgfmt from stating and causing a build error.
This change adds the MSVC path to the PLATFORM_ENV_BUILD_DIRS
so when we run the various tools the asan shared libs can
be found.
This updates OIDN to 2.3.0-beta. The final version is planned to be
released in time for Blender 4.2 Beta. The most relevant changes:
1. Much higher quality when denoising with accurate prefiltering in *high*
quality mode, but at the cost of lower performance (use *balanced*
quality mode to revert to previous *high* quality mode)
2. Added new *fast* quality mode for 1.5-2x higher performance viewport
denoising
3. Lazy device module loading to avoid potential stability issues caused by
drivers of unused devices
4. Release CUDA primary context as soon as the OIDN device gets destroyed
to prevent potential memory leaks
To enable 2 and 3, code changes are needed in Blender, to be committed
separately.

Without this canceling cppcheck part way through meant comparing old/new
log-files wasn't possible without manual renaming.
Now the new log-files are only written (and previous execution renamed
to ".old.log") once generating the log has completed.
This can cause crashes when loading incompatible plugins that happen to
be installed in one of the directories.
This change has been merged upstream, but there will likely be no stable
release in time for the next Blender release. So patch locally for now.

Support for building blender with clang on windows on x64 was added
years ago but given there are no active users support has crumbled a
bit.
This PR brings the build system back into working order but upstream
patches in openVDB are still required for a successful build see PR
#120317 for details.
Blender when build with clang the classroom scenes rendered on the cpu
with cycles is seeing a 5% reduction in render time on both an
AMD 7700x and an Intel 14900k.
This PR adds a cmake option `WITH_WINDOWS_EXTERNAL_MANIFEST`
which is off by default which addresses the following 2 problems:
The CI env occasionally fails to link the manifest into blender.exe
with mt.exe getting file in use error. The solutions mentioned online
vary wildly between, just rebuild, turn off your AV, use this magic
switch. None of them actually point to a root cause we can address.
When building blender with clang and the visual studio generator
it also somehow doesn't embed the manifest.
If the bots stay problematic this option can be turned on for the CI
environment, and will be automatically turned on when it detects clang
and the visual studio generator being used.

Various changes that simplify running cppcheck, comparing results
from the previous execution.
- Create a summary of the log that groups errors by type,
useful since some kinds of warnings tend to lead to errors in the
code more than others.
- Keep a copy of the previous runs logs - useful for comparisons.
- Log the output in the order of the files selected to check.
- Fix non thread-safe output sometimes mixing warnings from different
processes.
This cleans up our `TEST_SSE_SUPPORT` macro to only test
for SSE42 and passes the flags to the CMAKE_C/CXX_FLAGS
the cpu check module needed to move to its own folder since
the flags at the end of a CMakeLists.txt appear to be used
for all targets inside a CMakeLists file and cpu_check cannot
be build with sse42 flags.
This only affects Mac/Linux since MSVC has no buildflags
to target SSE42

MoltenVK original intent was to let developers work on a mac system developing
for the vulkan eco-system. MoltenVK doesn't support all the features that we
require and would require additional workarounds to be actually supported.
It is not expected that we will release Blender with MoltenVK for this reason.
But it still has value for shader developers to validate shaders on metal and
vulkan on a single platform.

The script to run cppcheck failed for most files in source/ because
of a syntax error in MEM_guardedalloc.h with attribute functions.
Workaround the error by including BLI_compiler_attrs.h directly.
Other changes:
- Specify c++17 / c11 standards for C++ & C.
- Resolve errors from undefined integer ranges.
- Set the check level to exhaustive so checks always run.
- Suppress noisy missingIncludeSystem warning.
- Move run-time compiler defines into a temporary include
which resolves argument quoting errors when cppcheck is used with
clang's parser.
"Own" (the adjective) cannot be used on its own. It should be combined
with something like "its own", "our own", "her own", or "the object's own".
It also isn't used separately to mean something like "separate".
Also, "its own" is correct instead of "it's own" which is a misues of the verb.
Exact an exact match with Clang broke building when the compiler ID
was "AppleClang", reverting parts of [0].

* Only works on machines with a Qualcomm Snapdragon 8cx Gen3 or above.
Older generation devices are not and will not be supported due to
some driver issues
* Requires VS2022 for building.
* Uses new MSVC preprocessor for sse2neon compatibility.
* SIMD is not enabled, waiting on conversion of blenlib to C++.

* VS2022 is required.
* Only OpenPGL and DPCPP are disabled, other libraries are supported.
* Embree is built with LLVM and VS2019 tools, and for that reason has
its own cmake file as it is quite different.
* TBB and USD patches should become obsolete once these are upstreamed
and Blender upgrades to the latest versions.
