feat: allow installing multiple envs at once

[tdejager]

Allow installation of multiple envs at the same time. Eg:

pixi install -e default -e other

[Glatzel]

Can you also add an option like pixi install --all to allow installing all environments at once?
It will be useful when initializing a project.

Yes for sure! Was thinking I'll wait till someone asks for it, which was pretty soon 😄

Ok, added this!

[tdejager]

I've also added a message, what environments are installed, install is the only CLI command doing this currently. But when I was testing it out with multiple envs, it got a bit weird not having this. @ruben-arts @Glatzel wdyt?

Edit (eg):

> Installed environment: test!
✔ Project in /Users/tdejager/development/prefix/pixi/examples/flask-hello-world-pyproject is ready to use!

Hi, tdejager.
I got a thread 'main' has overflowed its stack in win pc. Maybe envs should be installed in order instead of parallel?

Hi, tdejager. I got a thread 'main' has overflowed its stack in win pc. Maybe envs should be installed in order instead of parallel?

That's weird, they are installed concurrently not in parallel. Could you share your pixi.toml?

And does it also happen if you specify one or two environment e.g: -e a -e b.

[Glatzel]

Here is my pixi.toml.
Both pixi install --all and pixi install -e py311 raise thread 'main' has overflowed its stack. I also tried examples/flask-hello-world-pyproject, and got the same problem.
If move numpy to [dependencies], it works fine.

[project]
name = "Install-Multi-Envs"
platforms = ["win-64"]
channels = ["conda-forge"]

[dependencies]
python = ">=3.10"
[pypi-dependencies]
numpy = ">=1.23"
[feature.py311.dependencies]
python = "3.11.*"
[feature.py312.dependencies]
python = "3.12.*"

[environments]
py312 = ["py312"]
py311 = ["py311"]

I think this installed environments message is a good hint for me. Besides, maybe we can have a cli command for getting this message, like pixi list --installed-environments. But I am worried that users will confuse this command with the existed pixi list --environment command.

I like the changes, just a few points

[tdejager]

@Glatzel does this happen with 'main' as well? I can't really imagine these changes causing this..🤔

Well, I tried the pixi install command and raised the thread 'main' has overflowed its stack problem, seems there are some bugs in the current main branch.

Also tested in version 0.22.0, did not find this problem.

Okay, so it will not block this PR but a serious bug nonetheless, could you make an issue? Thanks for helping with the initial debug!

No problem. I have created this issue in #1414.
