Nathan Whitaker d4d3a3c54f
fix(node): Implement fs.lchown (and process.getegid) (#24418)
Closes https://github.com/denoland/deno/issues/21260.
Part of https://github.com/denoland/deno/issues/18218.

Implements `node:fs.lchown`, and enables the node_compat test for it.
The test uses `process.getegid`, which we didn't have implemented, so I
went ahead and implemented that as well to get the test working.
