feat: Pyodide improvements: version setting, standalone environments (#2002)

* Fix a typo: pyoodide ➡️ pyodide

* Add `pyodide_build_version` attribute

* Add version to xbuildenv log step

* Add version to Emscripten log step

* Use `pyodide-build`'s version for updating constraints

* Bump Pyodide constraints by updating `pyodide-build`

* Add a schema for `pyodide-version`

* Update Pyodide constraints

* Bump `pyodide-build` to new 0.29.0

* Test out another Pyodide identifier

* Update outdated Pyodide constraints

* Add Pyodide version to temp directory name

* Remove Pyodide 0.26.1 from build configurations

* Retrieve + validate + install specific xbuildenvs

* Test wheel builds with Pyodide 0.26.2

* Add correct Pyodide version to identifier temp dir

* Don't pre-call Pyodide xbuildenv search

* Fetch just the stable Pyodide versions

* Refactor search + validation + install into one step

* Move all of it under a lock

* Reorder xbuildenv installation

* Add env and cwd to xbuildenv search call

* Temporarily lower to 0.26.2 target

* Separate out search, validate, install; again

* Run xbuildenv search in `CIBW_CACHE_PATH`

* Remove prior `PYODIDE_ROOT` env vars, copy envs

* Validate doesn't need to depend on searching

* Add file lock when searching xbuildenvs

* Test the original version: 0.26.1

* Update Pyodide constraints

* Update constraints for `pyodide-build` 0.29.0 again

* Bump Pyodide from version 0.26.1 ➡️ version 0.26.4

* Add note on compatibility for macOS + other archs

* Note Pyodide version for Pyodide identifier

* Docs about `CIBW_PYODIDE_VERSION`

* Don't fetch just the stable versions

* Discard a variable that's not used later

* Rename `search_xbuildenv` ➡️ `get_xbuildenv_versions`

* `validate_xbuildenv` ➡️ `validate_xbuildenv_version`

* Replace ordered comment, add newline

* Capitalise: "pyodide" ➡️ "Pyodide"

* "work" ➡️ "may succeed"

* Add another job to test a custom Pyodide version

* Handle "v"-prefixed + non-prefixed versions

* Convert to a proper toml-able option, and remove some hardcoded versions

This removes the enscripten and pyodide-build version specs from
pyproject.toml - pyodide-build is spec'd in the constraints file, and
the emscripten version can be read from the pyodide-build output.

* Add a schema entry

* Add docs for CIBW_PYODIDE_VERSION

* Rephrase

* Add tests for pyodide-version

* Apply suggestions from code review

* Add python_build_standalone util

* Hook up to python-build-standalone, removing dependency on host python

* Remove python hard-code in action.yml

* Add log step

* Add workaround for https://github.com/pyodide/pyodide-build/issues/143

* Add emscripten pytest test

* Remove unneeded checks

* Fix a pytest invoke for emscripten

* Generate pyodide-build constraints from the pinned pyodide version

* Remove pyodide python-build-standalone workaround

* Fixup paths from newer version of pyodide-build

* Fix/skip some failing tests

* Use `python -m pytest` on pyodide, even on Linux

* Docs fixes

* Don't call the github API at runtime, cache the release assets instead

* Ignore pylint false positive

* Add version auto-updating for pyodide

* Add support for pyodide 3.13.

* Fix tests for multiple pyodide wheels

* Remove workaround for unreleased pyodide-build

* Rename to "test_pyodide"

* Fix pathname confusion

* Remove extra github actions job

* Fix expectation for test_abi_none

* Fix the custom_repair_wheel test to actually have clashing names

* Fix pinned version test

* Document test-command limitation

* Remove pyodide 0.28.0a1 for now

* Update constraints files

* Docs/test fixes post removing pyodide cp313

* Fix ABI test expectation

* Docs improvements

* Improve some comments

* Remove logic duplication

* remove pyodide special casing

* Refactor constraints code to use a utility script, circumventing import issues

* chore: nicer nox env
