Closure capture cleanup & refactor Follow up of #89648 Each commit is self-contained and the rationale/changes are documented in the commit message, so it's advisable to review commit by commit. The code is significantly cleaner (at least IMO), but that could have some perf implication, so I'd suggest a perf run. r? `@wesleywiser` cc `@arora-aman`
