Update mypy run_from to respect nested setups (#570)

Multi-language repos that do not include `pyproject.toml` at their
workspace root will require mypy to respect their relevant configs. This
uses the new `run_from` key to support this, and we can roll this out
for other linters as needed.

Will require a CLI version (and required version) bump once the relevant
changes are released.
