Additions to `import.meta`

[GeoffreyBooth]

Opening this issue per today’s TSC meeting. This is a spinoff from https://github.com/nodejs/node/pull/49246#pullrequestreview-1585722251:

• Are additions to import.meta semver-major or semver-minor?
• Should additions to this shared namespace require WinterCG and/or TSC approval?

An import.meta.node namespace was floated in https://github.com/wintercg/proposal-common-minimum-api/issues/50#issuecomment-1664274693, but Bun objected. I think if we want to create a proprietary namespace then we need another WinterCG proposal for the namespace itself.
