metadata: remove Distribution._local

FFY00 · FFY00 · commit b5c483af7f3a · 2021-10-30T17:22:22.000+01:00
Importing an external module is anti-pattern and very unexpected behavior. Furthermore, the specific builder implementation we are using will provision an isolated virtual environmnent and perform the build there, which is unwanted in various scenarious. Perhaps there was a time this helper was needed, but we can now remove this in favor of build.util.project_wheel_metadata[1].
