deps: make V8 10.2 ABI-compatible with 10.1

Create an unused deopt kind to replace `DeoptimizeKind::kSoft`, which was removed. This ensures that the layout of IsolateData doesn't change. Refs: v8/v8@1ff685d PR-URL: #42740 Reviewed-By: Jiawen Geng <[email protected]> Reviewed-By: Richard Lau <[email protected]>
