Eliminate well known symbols as a concept in the checker and rely on unique symbols (#42543)
* Eliminate well-known symbols in the checker: 2021 edition

* Actually update the lib text to say unique symbol, too (this is unneeded with compat code in place, but this makes goto-def make more sense)

* Add test showing mismatched symbol constructor type interop

* Add more test cases for some other related issues this fixes

* Revert computed name change

* Style comments
