fix(types): use TS interfaces only for public api

[dai-shi]

This mostly reverts #1012.
@typescript-eslint/consistent-type-definitions rule doesn't work for library code.

So, our new ground rule is:

• prefer interface for public api (always with export)
• otherwise, prefer type alias

close #1100
close #1103
close #1113

jotai and valtio should follow this too.

@dai-shi i'm wondering why interface is preffered over types for external public api

[dai-shi]

for complex types, type aliases will be inlined, which doesn't look nice.

See screenshot in pmndrs/jotai#1234 for example.

[dai-shi]
