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.
