wip: use pypa/installer to install wheels

[abn]

An initial step towards dropping pip to install packages. Once there is a more performant iteration of #5650 we should be able to replace PipInstaller with a NativeInstaller that uses a combination of build (to build wheels from source), EditableBuilder to install editable sources and installer to install wheels. The editable installs should already be doable.

In the interim, this is an experimentation for early feedback on using installer to install already available wheels. The initial results are quite promising. On my development environment, once the cache is populated, the following times were recorded for 10 iterations for the following command and pyproject.toml.

time for i in {1..10}; do rm -rf .venv/; poetry install; done

pyproject.toml

[tool.poetry]
name = "foobar"
version = "0.1.0"
description = ""
authors = ["Some One <some.one@somewhere.com>"]
readme = "README.md"

[tool.poetry.dependencies]
python = "^3.10"
aiohttp = "^3.8.3"
poetry-core = "^1.3.2"
tomlkit = "^0.11.6"
httpx = "^0.23.0"

[tool.poetry.group.dev.dependencies]
pytest = "^7.2.0"

[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"

Without patch

real    0m37.136s
user    2m37.909s
sys     0m13.516s

With patch

real    0m11.295s
user    0m10.434s
sys     0m2.567s

If enabling this we should allow for experimental as there could be edge cases around how platform wheels will be installed.

@neersighted think we briefly talked about this one a while ago.

Missed the changes added in #6205.

@sdispater you still actively working on that one?

[abn]

I am going to drop this one in favour of #6205 as that is more comprehensive.
