Remove superCallShouldBeFirst error (#37947)

* Remove superCallShouldBeFirst error

It seems redundant since TS gives an error on any use of `this` before
super, and non-`this` uses before `super` should be fine.

Fixes #37371

* Revert "Remove superCallShouldBeFirst error"

This reverts commit 3c09153c8a.

* error except for target:"esnext" && useDefineForClassFields
