MockEnv should not use paths of SystemEnv for paths that may be written to

We can now lock using the new lock file format as Poetry 1.2.2 has spent
sufficient time in the wild. A re-lock is also advisable as the full
release of Python 3.11 is here and we want to make sure to use any new
wheels in CI.

provider: discard any marker dependencies if the resulting marker after merging is empty, not compatible with the project's python constraint or not compatible with the set environment

subclasses of ValueError like UnicodeEncodeError have to be propagated (see #6784)

Bump `xattr` version to `0.10.0`.

This fixes #6891, which is not a problem with the user's environment as
suggested by the maintainer of xattr at xattr/xattr#108, but in fact the
problem of the package which was fixed by xattr/xattr#106.

Looking at the [changes in the version
bump](https://github.com/xattr/xattr/compare/v0.9.9...v0.10.0), there
does not seem to be any significant changes other than shabang
xattr/xattr#106.

This is an extension of
https://github.com/python-poetry/poetry/pull/6724. I think `pip install`
invoked by poetry should never ask for user input.

Motivation is that it happened to myself and a number of colleagues many
times that poetry got seemingly stuck while it was just waiting for a
user input because of a private pypi repository that needed
authentication.

I hope this is a valuable contribution to a tool I like a lot and would
like to use more and more :)

As written, it seemed to prioritize the older section notation without
clarifying that the older syntax still works but shouldn't be used. This
reorder visually prioritizes the preferred syntax as of 1.2.x while
clearly explaining what the old syntax is during this transition period.

The best next step here would be clearly defining the version in which
dev-dependencies will disappear.

Found some cases where tests were writing to the Poetry test runtime
environment rather than a mocked local directory. This is an issue,
since it meant that some tests were technically stateful when rerunning
locally.

Added in placeholders for those tests. Tested that this succeeds by
using a build where my Poetry venv was made entirely read-only.

https://github.com/python-poetry/poetry/actions/runs/3371708936 shows
that `set-output` is now deprecated.
https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/
shows the new way of exporting outputs.
