This lays the initial groundwork for enabling the
use of IsolateGroups.
Every isolate in V8 is created within a group. When pointer
compression is enabled, all isolates within a single group
are limited to a 4 GB shared pointer cage. By default, all
isolates in the process share the same group, which means
that when running with pointer compression, the entire
process would be limited to a single 4 GB shared pointer
cage. But, we can create as many IsolateGroups as we want,
limited only by the amount of virtual memory available on
the machine.

- Remove usage of deprecated V8::InitializeSandbox().
- External code space and pointer compression shared cage must
be enabled when pointer compression builds are enabled.
- We cannot enable the sandbox because that requires allocating
the array buffer backing stores in the sandbox - we currently
have many backing stores tied to pointers from C++ land that
are not even necessarily dynamic (e.g. in static storage).
Until we manage to get rid of all those, sandbox cannot be
enabled. Note that enabling pointer compression without
enabling sandbox is unsupported by V8, and can be broken
at any time.

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`

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.
```console
$ ./node benchmark/compare.js --runs 15 \

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.
