Some linux distroes install headers through their
package managers. When headers are locally installed
we'd like them to be used.
Add a build time configuration option
--use-prefix-to-find-headers that will will suggest to
node-gyp to look for headers based on the prefix
A PR to node-gyp will use this value when building
addons to automatially find and use the headers
if they have been installed locally

Enable V8's new maglev compiler by default on supported architectures.
This brings modest performance improvements for short-lived workloads
like CLI programs (see the linked issue) and brings Node.js's
configuration slightly closer to Google Chrome's.
I marked this change as semver-major because Maglev can theoretically
cause performance regressions, although I haven't seen an example of
that in the (somewhat limited) benchmarking I've done.
**Notable Change Summary:** V8's Maglev Compiler is now enabled by
default on supported architectures (https://v8.dev/blog/maglev). Maglev
improves CPU performance for short-lived CLI programs by around 8%.

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.

We should set v8_enable_webassembly=false when lite mode is enabled,
since v8_enable_lite_mode implies v8_jitless, and wasm currently
doesn't work with jitless. This is automatically handled in gn, but
seems to be not the case in gyp. Enabling lite mode without setting
v8_enable_webassembly=false leads to "Warning: disabling flag
--expose_wasm due to conflicting flags" at runtime.

- Use the `with` keyword for resource-allocating operations.
- Avoid using multiple statements in a single line.

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.

This commit adds the setting of an appname (configuration section
name), 'nodejs_conf', to be used when reading OpenSSL configuration
files.
The motivation for this is that currently the default OpenSSL
configuration, 'openssl_conf', element will be used which may be
undesirable as it might configure OpenSSL in unwanted ways. With this
commit it is still possible to use a default openssl.cnf file but the
only section that Node.js will read from is a section named
'nodejs_conf'.

`icu_locales` is generated by joining values from `set` data structure.
However, `set` doesn't guarantee an order, so the result of
`icu_locales` is not determined. For example, the result value could be
'en,root' or 'root,en'. This fix makes it deterministic.
The main reason of this fix is to restore the reproducibility of the
build because the value of `icu_locales` is embedded into `node` binary.

the renaming V8 bugs before we make it available to more users via
