fix(types): patch awaited for ts < 4.5

[dai-shi]

close #1398

We used have our custom Awaited, but it doesn't work with TS < 4.0.
This PR eliminates the custom one, and uses the built-in one available since TS >= 4.5.
For older versions, we patch with a limited (non-recursive) Awaited type.

I'm thinking about using built-in Awaited for ts >=4.5 and patched one otherwise,
which should fix #1242 @Newbie012.
