Gyp generated build files can be built in either Release/Debug mode.
- make: single directory, two configurations by cli:
`make -C out BUILDTYPE=Release` and `make -C out BUILDTYPE=Debug`.
- msbuild: single directory, two configurations by cli:
`msbuild node.sln /p:Configuration=Release` and
`msbuild node.sln /p:Configuration=Debug`.
- ninja: two directories in `out/`, build with
`ninja -C out/Release` or `ninja -C out/Debug`.
Variables that changes with either Release or Debug configuration
should be defined in a configuration level, instead of the root level.
This fixes generating invalid build files.
Additionally, `v8_gypfiles/toolchain.gypi` duplicates defines in
`v8_gypfiles/features.gypi`. Remove the duplications in
`toolchains.gypi`

Most changes are gated by the `clang==1` condition to avoid breaking
MSVC builds.
Select C/C++ language standard with ClCompile options.
This avoids passing the `-std:c++20` flag while compiling C code.
Do it only under clang option to avoid breaking addons until node-gyp
supports the new LanguageStandard options.
Disable precompiled header configuration for now as it doesn't seem to
work with clang-cl.
Disable C++20 warnings emitted by the Visual Studio C++ STL.
They're very noisy and not our responsibility to fix.

checks made by the configure script.
- Replace gyp conditions with `llvm_version` and "0.0" with conditions
that use the `clang` variable.

This patches V8 v12.3 for Windows, by fixing multiple compilation
errors caused by V8 being a Clang-oriented project. There are various
types of errors fixed by this going from changing `using` directives
and renaming to overcoming the differences in which Clang and MSVC see
templates and metaprogramming.
The changes introduced here are strictly meant as a patch only, so they
shouldn't be pushed upstream.

This adds a configuration flag to enable V8's Maglev compiler.
Unfortunately compilation fails unless you have clang-14+ or gcc-13+,
but I sent a patch for that upstream. Other than that, it builds and all
tests pass locally on my x86-64 Linux machine.
The gn scraper regexes were broken preventing the compilation from
linking. Fix them. As a drive-by, also add additional conditionals for
compilation on 32-bit arm.

Speed up child_process.spawn by enabling the new V8 build flag which
makes fork/exec faster.
Here are the results of running the existing benchmark. Note that this
optimization helps more for applications with larger heaps, so this is
somewhat of an underestimate of the real world performance benefits.

Python 3.9 on IBM i now properly returns "os400" for sys.platform
instead of claiming to be AIX as it did previously. While the IBM i PASE
environment is compatible with AIX, it is a subset and has numerous
differences which makes it beneficial to distinguish, however this means
that it now needs explicit support here.

In the upstream, V8 also disables snapshot compression on the
desktop by default because the size reduction is not worth the
performance hit.
https://chromium-review.googlesource.com/c/v8/v8/+/3275554
Locally the binary size of Node.js is increased by ~2.7MB
(+3.2%) with a significant speedup in startup after snapshot
compression is disabled on macOS.
Also adds a --v8-enable-snapshot-compression to configure.py for
users who prefer a size reduction over speedup in startup.
Ideally we should implement our own compression for the source
code + the code cache + the snapshot instead of relying on V8's
builtin compression for just the snapshot.
