Subject: [PATCH 1/2] tests: Don't scan build/scratch directories for tests

This was interfering with running tests locally, pytest
- scanned .git/ & tried to parse content as Python source
- scanned build/ and found duplicates of e.g. wasmtime/_config.py

This restores the relavant default globs for norecursedirs, that
were previously overridden.

https://docs.pytest.org/en/7.1.x/reference/reference.html#confval-norecursedirs

E.g.
```

Subject: [PATCH 2/2] tests: Add noxfile.py to run tests locally across Python
 versions

Nox is a Python CLI tool for running tests or other build/project management
tasks. It's invoked as
- `nox` or `python3 -m nox` - run every session defined in noxfile.py
- `nox --list` - list sessions defined
- `nox -s <session>` - Run a particular session
- `nox -p <python,...> - Run sessions the use the given python version(s)

If desired checks such as MyPy or style can also be included.

See https://nox.thea.codes/en/stable/index.html
