* refactor: add a wrapper for wrangling uv handles. Part 1 of a fix for #25248, #22069. Place the uv_asyncs owned by NodeBindings, ElectronBindings inside a new UvHandle wrapper class which manages uv_handles' need for their closed() callback to be invoked before the handles' memory can be freed. * chore: make lint happy * refactor: use DCHECK_EQ() instead of DCHECK() * refactor: fix oops
