* 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
