Update to libnode 22 LTS.
Bumps zlib as well, since libnode depends on a newer version.
Took me the entire day, but here we go. This is the packaging side of updating libnode 18 to libnode 22. I don't think there are any other build system or packaging changes to do; Everything should just work™ there.
To build, don't forget to bump the cppstd to 20:
conan install . -s build_type=Release -b missing -pr:b=default -of build -s compiler.cppstd=20
The first build error is:

libnode22 also builds on macOS, which version 18 doesn't without patches due to it looking for the wrong Python executable.
it seems that abseil is causing issues? It is a dependency of webrtc-ap-2. Do we need to update it as well?
I figured it out, the CXX_STANDARD was reset to c++17, so std::partial_ordering was not available anymore for abseil -> webrtc-audio-processing -> overte
ERROR: There are invalid packages:

I finally built it, but after starting it kinda just freezes and menu on the top of the window doesn't work at all.

When I set world URL to empty string, the client is still extremely slow, and going to tutorial grinds it to a halt.
Here's a CPU utilization graph from a run with empty string:
It looks like V8 is accessing some sort of a file continuously, which makes it extremely slow?
The issue is present only on the Debug builds. Release builds start correctly, but tutorial is broken. Spawn position is always 0,0,0 instead of proper one. The issue is visible in the logs:

Maybe libnode/V8 has some build flags on debug that are causing issues?
The issue should not be the build flags, as I can not find any problem with that?
I use libnode 22.20 and the conan package shows 22.17.1. Should we update the package to see if it resolves itself?
I have tried to create my own flame graph (with and without Debug) and it seems normal again? I could not reproduce that issue at all.
The flamegraph (and a friend of mine) also suggests, the issue lies in the kernel and/or setup instead of v8? I have no idea how else to debug that, especially because I couldn't reproduce the issue...
After looking into the code flow, I have seen the reason it calls pthread_getattr_np over and over is because a thread_local variable is always NULL? (assumed call-site of pthread_getattr_np1, and where it should've been cached2)
Which would mean, the performance is being degraded by the Isolate::Enter function in a new thread each time it is called? @ksuprynowicz do you know if that could be true?
