Tsify tools (mostly) (#7018)

This includes among others:
 - Proper tsification of various tools code,
 - Elimination of the `CompilationInfo2` type,
 - Use of `CompilationInfo` instead of `Record<any, any>` in some places
 - These lines in CompilationResult:
```
    // Temp hack until we get all code to agree on type of asm
    asm?: ResultLine[] | string;
```

The next task would be to get all code to agree on the type of
CompilationResult.asm, thereby enabling fixing of most the remaining
TSification.
