[whatwg/dom] Pass better parent/root information to (re)moving steps. (PR #1450)

For removing steps and moving steps, instead of passing only oldParent (which is null when the removed node is not the root of the removed subtree), pass both oldParent (never null) and isSubtreeRoot.

This is the DOM spec part of the fix for https://github.com/whatwg/html/issues/12098
For the HTML spec change see https://github.com/whatwg/html/pull/12144

- [X] At least two implementers are interested (and none opposed):
   * Chromium
   * Gecko (assuming https://github.com/whatwg/html/issues/12098#issuecomment-3872487261 is sufficient)
- [ ] [Tests](https://github.com/web-platform-tests/wpt) are written and can be reviewed and commented upon at:
   * I think this *probably* doesn't need tests since previous implementors and test authors assumed that the spec said what this pair of PRs is updating it to actually say.
- [ ] [Implementation bugs](https://github.com/whatwg/meta/blob/main/MAINTAINERS.md#handling-pull-requests) are filed:
   * Chromium: …
   * Gecko: …
   * WebKit: …
- [X] [MDN issue](https://github.com/whatwg/meta/blob/main/MAINTAINERS.md#handling-pull-requests) is filed: Not needed.
