build(core): remove `main()` from specs (#21053)

`main()` function used to be needed to support dart, since dart
Does not allow top level statements. Since we no longer use dart
The need for `main()` has been removed.

In preparation for `Basel` and standardized way of running tests
we are removing `main()`

PR Close #21053
