Issue Description

Please see flutter/flutter#133195
Users are running into super slow cycles while debugging their Flutter apps

What is the fix

Avoid searching static functions in the imported libraries, Searching in the imported libraries could be very slow as they can be huge (e.g. the whole Flutter framework)

References to members are fully resolved in kernel. So, when
looking for a static function in the library scope, there is no need to
search in the imported libraries.

Why cherry-pick

Flutter developers are running into this issue while debugging their apps and is hurting their productivity

Risk

low
