refactor(utils): atomWithObservable

[dai-shi]

close #1404

error handling was already supported, so what this PR does are:

• add more tests with error handling.
• better error handling code eliminating Promise.reject().
• refactor the entire code with our recent experience with jotai/query and jotai/urql.
• options type is slightly changed to avoid confusion.

This new option is still an undocumented one. It only exists to avoid memory leaks with concurrent rendering. we are not sure what's the best practice. Hmm, maybe we should add unstable_ prefix.
